Reducing carbon-dioxide emissions is primarily a political problem, rather than a technological one. This fact was well illustrated by the fate of the 2009 climate bill that barely passed the U.S. House of Representatives and never came up for a vote in the Senate. The House bill was already quite weak, containing many exceptions for agriculture and other industries, subsidies for nuclear power and increasingly long deadlines for action. In the Senate, both Republicans and Democrats from coal-dependent states sealed its fate. Getting past these senators is the key to achieving a major reduction in our emissions.

Technological challenges to reducing emissions exist, too. Most pressing is the need to develop the know-how to capture carbon dioxide on a large scale and store it underground. Such technology could reduce by 90 percent the emissions from coal- fired power stations. Some 500 of these facilities in the U.S. produce 36 percent of our CO2 emissions.

But these plants aren’t evenly spaced around the country. And therein may lie the key to addressing the political and technological challenges at the same time. If the federal government would invest in carbon capture and storage, it could go a long way toward persuading politicians in every state to sign on to emission reductions.

I’ll get to the specifics of the technology shortly. But first, consider how the costs of emission reduction fall hardest on certain parts of the country: A carbon tax levied on all major sources of released CO2, the approach favored by most of the environmental community, would make energy from coal-fired power plants cost more. To make a significant difference, such a tax would have to amount to $60 a ton.

Midwest Carbon Footprint

As a result, gasoline prices would rise 26 percent, and natural gas for household usage by 25 percent, nationwide. Rich and urbanized states could probably tolerate this. The West Coast, with its hydroelectric power, and the Northeast, which relies to a large extent on natural gas, could most easily absorb the associated increase in energy costs.

But the price of energy in the rural, Midwestern states would more than quadruple because of their large carbon footprint. Midwesterners get most of their electricity from coal; they drive relatively long distances to get to work, shopping and entertainment; and rural homes and buildings use more energy for heating and cooling.

One carbon-tax proposal now being considered is a “cap and dividend” plan that would send the tax revenue back to all U.S. citizens equally. But that would also favor the rich states that are less dependent on driving and coal.

It would be more helpful for the coal-dependent states if the federal government would use revenue from a carbon tax to help develop the technology for carbon capture and storage.

And that brings us to the technological challenges: No plant of any size with the capacity for CCS yet exists, but it has been demonstrated to work at small scales. Three different processes for capturing the CO2 are being tested, and scaling them up for 500-megawatt or 1,000-megawatt facilities should be possible.

For two years, the Mountaineer plant in New Haven, West Virginia, has been capturing and storing a tiny amount of its CO2 -- 2 percent of it -- but plans to build a full-scale carbon-capture plant here have been abandoned. Because Congress has dropped any idea of imposing a tax on carbon emissions, the investment doesn’t make sense.

A large plant in Edwardsport, Indiana, was being constructed with the expensive gasification process that makes it easy to add carbon-capture facilities, but it, too, has been shelved.

China may finish its large demonstration carbon-capture plant before the U.S. gets any model up to scale. Others are planned in Europe, and a small one is operating in Germany. This plant has been unable to get permission for underground storage, so it is selling some of its CO2 to soft-drink companies and venting the rest.

Subterranean Storage

Storing captured CO2 is eminently possible, too. For 15 years, the Sleipner facility in Norway has been storing 3 percent of that country’s CO2 underneath the ocean floor, with no appreciable leakage. Algeria has a similar facility, the In Salah plant, operating in the desert.

One storage strategy under consideration in the U.S. is to inject captured CO2 into huge basalt formations off both the east and west coasts. Inside the basalt, the carbon gas would gradually turn into bicarbonate of soda.

There are other ways to dispose of carbon dioxide. It has been used for enhanced oil recovery for many decades without any danger, and has been effectively stored in depleted oil reservoirs. (The gas is dangerous only in high concentration.)

It remains uncertain how much of the captured CO2 might leak during storage. Even if this were as much as 10 percent, however, it would mean that 90 percent of it would stay underground.

As CCS technology develops, it will have to be made more efficient so that it uses less energy. As it is, the capture phase is expected to require that a power plant burn 20 percent to 25 percent more coal than it otherwise would.

The technological challenges may explain why energy companies haven’t lobbied for subsidies to develop CCS. The electric-energy sector isn’t known for innovation and risk- taking. Just look at the U.S.’s outdated power grid.

But the federal government could pay for the subsidies through a tax on carbon. Such a levy would have other advantages, too: It would raise the cost of energy to reflect the damage that burning coal and oil now do to the environment, and spur the development of renewable sources.

If states with large carbon footprints can’t accept such a tax, the CCS subsidies could be paid from the general fund. The cost to build coal-fired power plants with CCS technology is estimated to be about $5 billion to $6 billion -- about the price of a single nuclear power plant. The total price for the U.S.’s 500 large plants would be $250 billion. That’s as much as the planned modernization and expansion of our missile defense system over 10 years.

But it would slash our carbon emissions by at least 20 percent. There is no other politically possible way to cut CO2 as much, and as quickly -- in a decade or two. And devastating climate change is far more likely than a missile attack.

U.S. investment in CCS technology could also induce China and Europe to follow suit. And this would allow the world time for renewable-energy technologies to mature -- to the point where we could do away with coal burning altogether.

Emerging nation-states like Libya and Palestine are constrained by local elites integration in socio-economic networks.

----

Attention is fixed on Mahmoud Abbas' application for Palestinian statehood at the United Nations, and on the capture of state power by Libyan rebels. Have we forgotten to ask whether and under what conditions the nation-state is a viable political vehicle for justice and liberation?

A world composed of nation-states is less than seventy years old. Yet the ideal of "national liberation" dominates the political imagination of many oppressed peoples. Such a politics of emancipation has dire limits because serious power is organised and exercised on a global scale.

Before World War II, the world was made up mostly of empires and colonies. A state of their own seemed to promise freedom and recognition to colonised populations. This is because the world of nation-states masquerades as a world of sovereign equals. Each nation-state supposedly rules its own territory and people, free from outside interference.

Only for the others

This was the ideology behind the United Nations, which was conceived and organised by the Western allies during World War II. The war aims of the US and the UK, as expressed in the Atlantic Charter of 1941, included the idea that all "peoples" had a right to self determination. Winston Churchill was quick to claim that this only applied to those in Nazi occupied Europe, not the subject peoples of the British Empire.

But Churchill was a man of the old world. Already the US had pioneered in Latin America and in its "open door" policies towards China modes of intervention and informal rule that recognised the political independence of subordinate states. The diplomatic historian William Appleman Williams used the term "Anticolonial Imperialism" to describe what the US was up to.

Empires always operate in and through some kind of local administration, whether a colonial state, a kept Raja, or an informal relation with a client power. In mature colonies, much of the day to day work of government was carried out by indigenous people, trained up as civil servants, police, and soldiers. Businesses were often operated and even owned by locals.

Occupying such a colony with imperial officials was not only expensive, it caused friction and generated resistance. Why not give local power brokers a somewhat larger cut (but not too large) to run the place for you? The oppressed "nation" could celebrate "independence", the local elites could enrich themselves, and the imperial power could continue to enjoy the advantages of domination and unequal economic relations.

This was not only empire without colonies, it was an empire that could pose as a supporter of "national liberation".

The United Nations took this concept of the nation-state to a global level. The world came to be composed mostly of small, relatively weak states, each proudly sovereign and jealous of its prerogatives. But each one also enmeshed in the brutal and shocking disparities of wealth and power that have characterised global politics since the nineteenth century. Local elites prospered, while their people toiled away at subsistence level.

A nation-state organisation of the world offers advantages to those who want to sustain global hierarchies of power. It also poses immense challenges to those struggling for freedom.

The immediate problem is which group or set of interests will seize state power. Colonial borders encased many different peoples within the same territory, and divided others. Colonisation produced sectors of society which benefitted from and were in sympathy with imperial power in varying degrees. The result is intractable and recurring clashes of identity and interest.

These conflicts are evident now in Libya and they have fractured the Palestinian national liberation movement.

"Imagined Community"

Even in Europe, there was no "nation" behind the state to begin with. In myriad ways state power was used to create the "imagined community" of the nation, which often enough was a fiction propagated by a dominant ethnicity or social class.

It is one thing to build a nation-state while rising to world dominance, as in the West. It is quite another to do so when you are on the losing end of global inequities in wealth and power.

New holders of state power in the global South - even in a rich state like Libya - are profoundly constrained and face limited options. Local elites are often deeply enmeshed in economic, cultural and political networks that tie them to foreign powers and interests, Western or otherwise.

The usual outcome is some kind of neo-colony. A local political and economic class benefits from relations with outside powers and global elites, to the neglect of the ordinary people who brought them to power and of their political desires.

Such an arrangement takes many forms. One model is the resource rich country, which can sustain a hyper-wealthy elite, while keeping the masses in check with a combination of repression and bread and circuses. This is the likely fate of Libya, if it does not descend into internal conflict over the possession of state power and its benefits.

Another model is that of South Africa's Bantustans, "tribal" states that were given limited "independence". Their function was to outsource security. Like the Palestinian Authority, the Bantustans self-policed a restive population. They also served as a basis for the power and wealth of a local ruling class, connecting it to the larger order that oppressed everyone else.

None of this is to suggest that people seeking liberation should not seek state power. Among other things, the state has the potential to equal the scales between the public good and the private power of capital, foreign or domestic.

But it is to say that the seizure of state power cannot be the end goal of contemporary liberation politics. In the global South, to have a politics only about the nation-state is to play a game with dice loaded against you.

A liberation politics beyond the nation-state would from the beginning reach out to those in other societies struggling also for a just global order. In so much of both the global South and North right now, politics has been reduced to the servicing of narrow interests by cronies holding offices of state.

People around the world are suffering through the nadir of capitalism that is our times. Such circumstances offer possibilities for a local-global politics of liberation.

It is in the global South that liberation movements have the best chance of seizing local state power and its many advantages. At the same time, connections with global struggles for justice will give the free states of the South an international base, a source of power with which to resist becoming a neo-colony.

For it is ultimately only a just global order that long can sustain freedom and equality at home.

Russia watchers in the West cannot be surprised that Vladimir Putin is on his way back to the Russian presidency. Dmitri Medvedev was always his protégé, and there was no doubt that major decisions could not be made without his approval. This includes signing the New START arms control treaty, cooperating with NATO in Afghanistan and supporting U.N. sanctions on Iran — all of which should provide reassurance that Putin’s return won’t undo the most important accomplishments of the U.S.-Russia “reset.”

Yet the relationship with the West will inevitably change. For one thing, Putin can have nothing like the rapport his protégé developed with President Obama, which was built upon the two leaders’ shared backgrounds as lawyers, their easy adoption of new technologies, and their fundamentally modern worldviews.

The Bilateral Presidential Commission which Obama and Medvedev created and charged with advancing U.S.-Russia cooperation on everything from counterterrorism to health care may suffer. The relationship as a whole is not adequately institutionalized, and depends on the personal attention of Russian officials who will likely avoid taking action without clear direction from Putin, or who may be removed altogether during the transition.

Putin’s return to the presidency will also provide fodder for Western critics bent on portraying Obama and the reset as a failure, or dismissing Putin’s Russia as merely a retread of the Soviet Union.

These critics are wrong — today’s Russia bears little resemblance to what Ronald Reagan dubbed an “evil empire” — but Putin has been far more tolerant of Soviet nostalgia than his junior partner, and his next term will surely bring a new litany of quotations about Soviet accomplishments and Russia’s glorious destiny that will turn stomachs in the West.

Although he has spent his entire career within the apparatus of state power, including two decades in the state security services, Putin is at heart a C.E.O., with a businessman’s appreciation for the bottom line. Western companies already doing business in Russia can expect continuity in their dealings with the state, and it will remain in Russia’s interest to open doors to new business with Europe and the United States. The next key milestone for expanding commercial ties will be Russia’s planned accession to the World Trade Organization, which could come as soon as December.

At home, Putin faces a looming budget crisis. As the population ages and oil and gas output plateaus the government will be unable to continue paying pensions, meeting the growing demand for medical care, or investing in dilapidated infrastructure throughout the country’s increasingly depopulated regions.

This means that while Putin will seek to preserve Russia’s current economic model, which is based on resource extraction and export, he will be forced to assimilate many of his protégé’s ideas for modernizing Russia’s research and manufacturing sectors. Medvedev’s signature initiative, the Skolkovo “city of innovation,” will likely receive continuing support from the Kremlin, although it will have little long-term impact without a thorough nationwide crackdown on corruption and red tape.

Putin’s restored power will be strongly felt in Russia’s immediate neighborhood, which he has called Moscow’s “sphere of privileged interests.” Even though Kiev has renewed Russia’s lease on the Black Sea Fleet’s Sevastopol base through 2042 and reversed nearly all of the previous government’s anti-Russian language and culture policies, Ukraine is unlikely to win a reprieve from high Russian gas prices. Putin will also continue to press Ukraine to join the Russia-dominated customs union in which Kazakhstan and Belarus already participate. He may also take advantage of Belarus’s deepening economic isolation and unrest to oust President Aleksandr Lukashenko in favor of a more reliable Kremlin ally.

Putin and Medvedev have been equally uncompromising toward Georgia. Both are openly contemptuous of Georgian President Mikheil Saakashvili, and it is unlikely that any progress on relations can occur until Georgia’s presidential transition in 2013.

Putin has good reason to continue backing NATO operations in Afghanistan to help stem the flow of drugs, weapons and Islamism into Tajikistan, Uzbekistan and Russia itself. Moreover, as China extends its economic hegemony into Central Asia, he may find America to be a welcome ally.

Putin appreciates the advantages of pragmatic partnerships and will seek to preserve the influence of traditional groupings like the U.N. Security Council and the G-8 while at the same time promoting alternatives like the Shanghai Cooperation Organization and the Brics.

The succession from Putin to Medvedev and back again was decided behind closed doors, and the formal transition of power is likely to take place with similar discipline. This should offer the West and the wider world some reassurance. Putin’s return to the presidency is far from the democratic ideal, but it is not the end of “reset.” Many ordinary Russians support him because he represents stability and continuity of the status quo and, for now, that is mostly good for Russia’s relations with the West.

After 9/11, the administration of US President George W Bush initiated the era of the global war on terror. For many, this was a misguided response to terror attacks. But before the decade was over, US forces invaded two countries and are now fighting shadow wars in Yemen, Somalia, and Pakistan, while an air war continues in Libya. Pentagon commands cover the entire planet, and US military assistance programmes are active in almost every country.

 Wars reorder politics and values. They remake that which is taken to be true and right. They render the world unrecognisable from what it was when the balloon went up. That is why epochs of world history are so often marked off by the dates of wars. How should we understand the era of 9/11? In what historical timeline does it belong?

It is useful to begin by recalling some of what seemed true on September 10, 2001. The US enjoyed the unquestioned global supremacy of the "unipolar moment". The "end of history" beckoned, in which liberal democracy and free markets promised peace and prosperity everywhere for all time. The West and its international organisations managed the world, ultimately for the general good. Globalisation was bringing people closer together.

Today, each of these verities lies broken. The failure to understand the 1990s and the significance of the end of the Cold War has left us unable to understand what has been happening in the decade since 9/11.

Renewed global military commitments have hastened an inevitable US decline. The unrestrained power of finance capital is wrecking economies and societies across the Western world. Europe lies prostrate, bereft of anything approaching serious leadership, mired in the divisive politics of austerity and racist, anti-immigrant populism. The great international institutions have sat on the sidelines of the crises roiling the world. The communications technologies that were supposed to lead to mutual understanding instead assist revolts and terrorism, rioters and financial speculators, when they are not being used by states to spy on their own citizens, or by corporations to increase the number of consumer products people desire.

How is it that the received wisdom about the nature of world politics was so badly wrong? What did we fail to see and why?

The great conceit that blinds us is the idea that the powerful make history just as they please. We are particularly prone to this error when thinking about international politics. Assisted by opinion columnists and think tank gurus, we tend to view the world from the perspective of decision makers in the great powers. What should the West do about Libya? How should the US respond to state failure in Yemen or the Iranian bomb? What should the G-20 do about the debt crisis?

'Like cowboys at the rodeo'

In the domestic politics of our own countries, it is easy for us to see that politicians are like cowboys at the rodeo: hanging on for dear life before a force of nature tramples them underfoot. The "bull" that throws them could be a long-simmering social crisis, a downturn of the business cycle, or some series of events over which no one exercises control. The skill of the politician determines how long they can hang on, but we are left in little doubt as to where the real power lies.

We are forced to confront the underlying social structures, historical legacies, and economic relations that determine our fates. Human agency, too, has its say, but it is not only that of the great leaders that matter. Ordinary people and the social and political movements they create can drive events and force the "policymakers" to respond. But fate usually works against human purposes. Rarely do either the powerful or those who resist them achieve quite what they intended.

A wonderful example of the impoverished vocabulary with which we think about international politics is the idea that "Reagan won the Cold War". The vast apparatus that is a modern state is reduced to its leader - "Thatcher", "Gorbachev". Agency, the power to shape events, rests firmly in the hands of this leader, who is located in the global North. A range of violent struggles, fought almost entirely in the global South, are subsumed under one term which denies there was even a war at all. Most of all, a tidy end - 1989 - is imagined in which, needless to say, the good guys won.

Epoch-defining dates like 1989 or 9/11 invoke various imagined histories and geographies. But too often the dates with which we order world politics are curiously Eurocentric. It is European exploration, the French revolution, a Congress in Vienna, and German invasions, for example, which mark out the globe's historical eras: 1492, 1789, 1815, 1914, 1939.

We are thus singularly unable to grasp the global histories and social relations that delivered us to 9/11. Within the conventional terms of analysis of international relations, it is almost impossible to see the great social, political and economic struggles between the global North and South that have driven modern world politics. European imperialism and the prodigious efforts to incorporate ever more peoples and places, ever more domains of life, into the capitalist world system lie at the origins of these global histories.

It is crucial to underscore that imperialism, capitalism and the modern world they together did not simply emanate from Europe. They were joint productions with the non-European world, albeit amid unequal power relations. Imperialism requires collaborators, while capital needs labour. The first factories were not built in England, but in the Caribbean, producing sugar with African slaves.

The World Wars gutted European imperial power and unleashed struggles for independence across the global South, led almost everywhere by the anti-imperialist left. For over forty years revolutionaries and insurgents, death squads and soldiers, carried on a deadly combat.

The fall of the left

The global significance of 1989, broadly speaking, was the defeat in both the North and the South of the political left, of those political movements that sought to replace, contain, or redirect the expansive energies of capital in accordance with humane values.

During the Cold War, Western powers had to maintain social welfare systems at home lest communism begin to look attractive. The Soviets, meanwhile, tried and failed to demonstrate that they too could produce washing machines, refrigerators and other consumer items. With the collapse of the USSR, neoliberalism was unleashed and could begin in earnest to do away with welfare states in the West. "Shock therapy" was delivered to the former Soviet bloc countries, while the debt crisis was used to control many economies in the global South. No longer did the West have to secure Third World allies with lavish aid.

The defeat of the left produced two outcomes which have defined the last twenty years and will continue to make history over the next twenty.

The end of the Cold War did not mean the end of the dire social consequences of unrestrained capitalism. The grievances, the injustices, the poverty, the anger, the continued reduction of everything human to the bottom line, to something that can be bought or sold, all this remained, even intensified. But now it was not the left that would make political lemonade out of these lemons, but the right; not communists, but religious fundamentalists, both Christian and Islamic. This is where the Tea Party belongs, feeding on the misdirected resentments of those devastated by unregulated capitalism.

The second outcome of 1989 is a dramatic increase in the political power of capital. Across the Western world, but most especially in the US, politicians are in hock to Big Money, while corporate media fundamentally shapes political debate.

Blinkered worldview

The problem with this, as Karl Marx would have told us, is that while capitalists know what is in the interest of their specific business, they are unable to cooperate for the good of the system as a whole. To maintain a capitalist society of a kind anyone would want to live in requires tremendous public investment and infrastructure; a neutral, professional and active civil service; and a strong framework of effective, lawful regulation.

Few capitalists want to pay taxes for all this, or subject their industries to significant regulation. Give capitalists as a class too much political power, and they will enfeeble government with their special interests, lobbyists, and kept politicians. The consequence is the drama currently on display: the self-destruction of the West and its economies. It is plainly obvious that Western societies are in dire need of modernisation, investment, and strategies for growth and employment. But the political forces that might fight for these have long since been vanquished. Anguished experts like Paul Krugman are left accurately to foretell a doom that the political systems of the West willfully do nothing to avoid.

It is this self-inflicted crisis that drives the timing of the scale-down of the global war on terror currently underway. After all, nation-building at home or abroad requires taxes. Rather than occupying countries in a "forward strategy for freedom", as Bush termed the invasion of Iraq, the war on terror will transform into the police, spy and special operations war Western liberals had originally called for in 2001.

Unifying the eras of the Cold War, the 1990s, and the decade following 9/11, are reinvigorated efforts to control the politics, economies and populations of the global South in the wake of the collapse of formal empire in 1945. Wars of tremendous folly and human cost have marked this entire period, in Korea, Vietnam, Algeria, Mozambique, and across Central and Latin America, among others. Bush's travesties in Iraq and Afghanistan will likely bring this series to an historical close. The tentative approach to Libya is a transition to a future of reduced Western ambition in the global South.

The retreat of the West from extensive and effective political and military efforts to control the global South - a history which began in the 16th century - rings the death knell of Western world power. The decade since 9/11 is the penultimate chapter in this history.
