Matthew Kroenig's argument for preventive military action to combat Tehran's nuclear program -- "Time to Attack Iran" (January/February 2012) -- suffers from three problems. First, its view of Iranian leaders' risk calculations is self-contradictory. Second, it misreads nuclear history. And third, it underestimates the United States' ability to contain a nuclear Iran. When these problems are addressed, it is clear that, contrary to what Kroenig contends, attacking Iran is not "the least bad option." 

Kroenig's view of the way Iranian leaders are willing to take on risks is deeply incongruous. In his view, a nuclear bomb will push Tehran to block U.S. initiatives in the Middle East, unleash conventional and terrorist aggression on U.S. forces and allies, and possibly engage in a nuclear exchange with Israel. This would mean Iranian leaders are reckless: given the United States' conventional and nuclear superiority, any of these actions would provoke considerable retaliation from Washington. And, of course, a nuclear exchange with Israel would invite annihilation. At the same time, Kroenig suggests that Tehran would remain remarkably timid after a preventive strike from the United States. Presented with clear redlines, Iran would not retaliate against U.S. troops and allies or attempt to close the Strait of Hormuz. Kroenig's inconsistency is clear: If Iranian leaders are as reckless as he seems to believe, a preventive strike would likely escalate to a full-blown war. If they are not, then there is no reason to think that a nuclear Iran would be uncontainable. In short, a preventive attack on Iran can hardly be both limited and necessary.

Kroenig's argument misreads nuclear history at least three times. First, he writes that a targeted preventive strike would likely wipe out the nuclear program in Iran, as strikes against Iraq in 1981 and Syria in 2007 did in those countries. These comparisons are misleading. Recent research based on captured Iraqi documents demonstrates that the 1981 Israeli attack on the Osirak reactor, near Baghdad, actually spurred a covert nuclear weapons program at other sites. Indeed, Iraqi President Saddam Hussein remained determined to revive his nuclear program until he was removed from power in 2003. What prevented him from achieving that goal was the decade-long U.S.-led containment regime put in place after the 1991 Gulf War. The Iraqi case suggests that any attacks that do not depose the Iranian regime, too, would cause it to accelerate its efforts to acquire nuclear weapons. Kroenig's prescription might therefore precipitate the very outcome he is trying to avoid. 

As for Syria, Damascus' nuclear program was just budding. The country boasted only one exploratory facility, which was shattered easily by a single aerial bombing carried out by Israel in September 2007 under the cloak of night. But Iran's nuclear program is much more advanced and is already of industrial proportions. Any attack on Tehran would involve destroying numerous nuclear-program and air-defense targets, making it far more costly and less likely to succeed than the Israeli raid against Syria's Deir ez-Zor reactor. More, Iran's advanced program reflects Tehran's greater resolve to develop nuclear capabilities, so, post-attack, Tehran would be ever more likely to double down on developing a weapon. Furthermore, although Kroenig hopes that a targeted strike would destabilize the Iranian regime, there is no basis for such optimism. Being a civilian, parliamentary, oil-rich theocracy, Iran is relatively stable. Put simply, a preventive strike against Iran can hardly be both limited and effective.

Kroenig misreads history again when he considers a nuclear exchange between Iran and Israel. In his view, they "lack nearly all the safeguards that helped the United States and the Soviet Union avoid a nuclear exchange during the Cold War." Yet the United States and the Soviet Union avoided a nuclear exchange even during the hottest crisis of the Cold War, the Cuban Missile Crisis, at a moment in which Soviet retaliatory capability was still uncertain, there were no clear direct communication channels between the two leaderships, and Soviet experience managing their nuclear arsenal was no longer than five years. Moreover, the historical record shows that even young and unstable nuclear powers have avoided nuclear escalation despite acute crises. Pakistan and India avoided nuclear war in Kargil in 1999, as well as after the terrorist attacks targeting the Indian parliament in 2001 and Mumbai in 2008. When national survival is at stake, even opaque and supposedly "irrational" regimes with nuclear weapons have historically behaved in prudent ways.

Kroenig's final abuse of history comes when he posits a cascade of nuclear proliferation across the Middle East in response to an Iranian bomb. He mentions Saudi Arabia, and implies that Egypt, Iraq, and Turkey might all follow suit. Yet none of these states, which can count on U.S. support against Iran, nuclearized in response to Israel's nuclearization (against which they cannot count on U.S. backing, mind you). And more generally, the United States has a successful record of preventing clients from acquiring nuclear weapons in response to a regional enemy, such as South Korea and Japan in response to North Korean nuclear acquisition. (Washington agreed with Pakistani nuclearization in response to India.) 

Taking the long view, Kroenig's argument reveals an unwarranted skepticism about Washington's ability to contain a nuclear Iran. This skepticism is all the more surprising considering Kroenig's work on the benefits of U.S. nuclear superiority. Existing U.S. security guarantees, based on current capabilities, give allies little incentive to nuclearize. Egypt and Saudi Arabia are among the largest recipients of U.S. military support, and Turkey is a member of NATO. Reinforcing U.S. ties with friends in the region would be easier, cheaper, and less risky than attacking the Iranian nuclear program. 

Instead, the United States should heed the lessons of the North Korean nuclearization. Not so long ago, Washington had to face an aggressive regime in Pyongyang intent on developing nuclear weapons. The United States rejected a preventive strike in 1994 for fear that the outcome would be worse than its target's nuclear acquisition. This was the right decision. After North Korea acquired nuclear weapons, none of the consequences that Kroenig's argument would predict materialized. U.S. security guarantees contained Pyongyang and persuaded South Korea and Japan not to acquire nuclear weapons. Nobody believes that the world is better off with a bomb in North Korea -- but the record shows that it hasn't brought the end of the world, either.

Military action against Iran would be a profound strategic miscalculation. For all the talk of retrenchment, the U.S. military might remains the most powerful in the world, and it can successfully minimize consequences of an Iranian bomb, should one come to pass, by containing Tehran's ambitions, dissuading regional proliferation, and providing security assurances to its allies.

For the past two decades China has been a poster child of successful globalization, integrating with the world and in the process lifting millions of citizens out of poverty. But China’s integration into the world economy and global trends drive and constrain Beijing’s ability to manage growing social, economic and political challenges. 

The nuclear weapons news of late has been alarming. David Sanger reported in "The New York Times" on January 9 that Iran's top nuclear official had announced his country was near initiating uranium enrichment at a new plant. And the recent leadership change in North Korea means added uncertainty about one of the world's most unpredictable nuclear weapons states. Both developments mean the danger is rising that nuclear weapons or the means to make them will spread in this year.

The ominous news brings to mind a comment that Robert M. Gates made a few years ago while working as President Obama's Secretary of Defense. "If you were to ask most of the leaders of the last administration or the current administration what might keep them awake at night," he told me, "it's the prospect of a [nuclear] weapon or nuclear material falling into the hands of Al Qaeda or some other extremists."

I was interviewing Gates for a book about nuclear threats. The book, "The Partnership: Five Cold Warriors and Their Quest to Ban the Bomb," [Harper, $29.99] examines the acute state of nuclear dangers today, including the spread of nuclear materials and technology to unstable nations like Pakistan, North Korea and Iran. If a terror group like Al Qaeda is ever going to get its hands on a nuclear weapon, or more likely the fissile material needed to make one, the source is likely to be one of those three nations. North Korea and Pakistan have a frightening history of exporting nuclear weapons technology. Iran may be next.

Despite the denials of Iranian leaders, Tehran seems well on the way to building its first nuclear weapon. Iran already has enough enriched uranium to make several warheads once the uranium is raised to a higher level of enrichment. The enrichment process can move very quickly from a low level to high, bomb-grade levels. Some upgrading of known Iranian enrichment facilities are required to get there, and these changes would be visible to the outside world. Still, Iran may well have hidden enrichment programs already cranking out highly enriched uranium. If it does move openly to higher enrichment, Israel and the United States will be tempted to attack Iran's nuclear installations.

A simple but powerful nuclear weapon can be fabricated with just a small amount of highly enriched uranium. The hardest part of making a uranium bomb is producing highly enriched uranium, something that requires advanced, industrial-scale technologies beyond the reach of a terror group. But with just 60 pounds of highly enriched uranium, a small, savvy group of engineers with some basic laboratory equipment could construct a fission bomb in a garage. The bomb mechanism is so straightforward that the United States did not bother to test a uranium weapon before dropping one over Hiroshima in 1945. And it is not wildly improbable to imagine Iran giving highly enriched uranium to a terror group.

The continuation of the Kim dynasty in North Korea - now in its third generation with the recent installation of Kim Jong-un as the new supreme leader - does not augur well for more responsible behavior by North Korea. With its active nuclear weapons program, hunger for hard currency and record of selling nuclear weapons goods to Libya and Syria, North Korea is one of the most dangerous nations on earth.

While North Korea is unlikely to sell a nuclear weapon to a terror group, it could provide the materials and knowhow to make a crude but powerful bomb. The United States, for all its intelligence-gathering hardware like spy satellites, does not know a great deal about the North Korean program. Washington was surprised to learn in 2010 that North Korea had constructed a uranium enrichment plant outfitted with the latest centrifuge technology. News about the existence of the plant came from a group of American scholars who were shown the facility during a visit to the North Korean nuclear complex at Yongbyon.

The plant is not a problem if it is producing low enriched uranium to fuel a small, light water reactor. But the plant could be used to produce highly enriched uranium. The rapid construction of the plant - it was built in just 18 months - suggested that the North Koreans might have honed their techniques at another enrichment facility, as yet undetected by the United States.

I recently asked my Stanford colleague Sig Hecker, one of the scholars who visited the enrichment plant in 2010, to outline what to watch for in the North Korean weapons program in coming weeks to determine if the new leadership is planning any change in nuclear policy and/or operations. Sig served as director of the Los Alamos National Laboratory 1986-1997. He has been a frequent visitor to North Korea, one of the few Americans to get a first-hand look at the North Korean nuclear program.

His response:

I believe that there will be a period of quiet on the diplomatic front, both for mourning and to rethink strategy. Just before Kim Jong-il died, American and North Korean diplomats came close to an agreement of American food aid in return for some concessions on the nuclear program (some reports indicated that Pyongyang would stop enrichment - but I have yet to hear official confirmation from the UnitedStates - and we never may). What to look for is to see when North Korean diplomats are ready to re-engage with Americans in quiet bilateral talks, mostlikely in China.

On the technical front: I would expect "normal operations" at Yongbyon. That means they will continue with the experimental light water reactor construction- although little will be seen from overheads because it is winter time. Much of the interior components will be fabricated in shops. I also expect them to continue with operations of the centrifuge enrichment facility - either to make more low enriched uranium for reactor fuel or to get the facility to operate fully (which it may not have been when we visited). Both of these operations will continue regardless of which way Pyongyang eventually decides to go with the nuclear program. I don't see any reason why they would cut back on these operations now.

As for potential provocative actions - they could prepare for another nuclear test -- but that is highly unlikely, if for no other reason than it is winter. Their tests occurred in October 2006 and May 2009. Nevertheless, the third test tunnel appears to have been dug some time ago (South Korean news reports and overhead imagery) and one should watch closely for activity at the test site (particularly come spring). We should also look for potential missile tests - the new launch site on the west coast should be watched for another potential long-range missile launch. (They have had three attempts from the old launch site in the east: 1998 over Japan, 2006 a complete failure, and 2009 two out of three stagesworked.) They also have not flight-tested the Musudan road-mobile missile."

It would not surprise me if North Korea conducted another nuclear test in 2012. If Kim Jong-un is looking for a way to flex North Korean military power and remind his impoverished people that their nation matters to the rest of the world, detonating a nuclear weapon will do the trick.

Iran's nuclear program will also likely generate news and international anxiety this year. Iranian threats to attack US naval vessels in the Persian Gulf may seem self-defeating, but a military confrontation between Iran and the United States is not out of the question.

There is no greater danger to American and global security than the spread of nuclear weapons and the means to make them.

From Harper Collins publishers:

Offering a clear analysis of the danger of nuclear terrorism and how it can be prevented, The Partnership sheds light on one of the most divisive security issues facing Washington today. Award-winning New York Times journalist Philip Taubman illuminates our vulnerability in the face of this pressing terrorist threat—and the unlikely efforts of five key Cold War players to eliminate the nuclear arsenal they helped create. Bob Woodward calls The Partnership a “brilliant, penetrating study of nuclear threats, present and past,” and David Kennedy writes that it is “indispensable reading for all who would understand the desperate urgency of containing the menace of nuclear proliferation."

Book Description

A terrorist attack with nuclear weapons is the most dangerous security issue America faces today—and we are far more vulnerable than we realize. Driven by this knowledge, five men—all members of the Cold War brain trust behind the U.S. nuclear arsenal—have come together to combat this threat, leading a movement that is shaking the nuclear establishment and challenging the United States and other nations to reconsider their strategic policies.

Illuminating and thought-provoking, The Partnership tells the little-known story of their campaign to reduce the threat of a nuclear attack and, ultimately, eliminate nuclear weapons altogether. It is an intimate look at these men—Henry Kissinger, George Shultz, Sam Nunn, William Perry, and the renowned Stanford physicist Sidney Drell—the origins of their unlikely joint effort, and their dealings with President Obama and other world leaders. Award-winning journalist Philip Taubman explores the motivations, past conflicts, and current debates that drive, and sometimes strain, their bipartisan partnership. Through their stories, he examines the political and technological currents that shaped nuclear strategy during the Cold War—including the 1986 Reykjavik summit, at which Reagan and Gorbachev narrowly missed a landmark agreement to eliminate nuclear weapons—and illuminates how the end of that conflict gave rise to the dangerous realities of today. He reveals the heated discussions taking place in Washington and in nuclear-weapons laboratories, and spotlights current threats and the frantic efforts of America and its allies to prevent the spread of fissile materials.

Meticulously researched and compellingly told, The Partnership demands that we turn our attention to an issue that has the potential to alter our world order. Philip Taubman has provided an important and timely story of science, history, and friendship—of five men who have decided the time has come to dismantle the nuclear kingdom they worked to build.

Critical Praise for The Partnership

“The Partnership artfully weaves the threads of five notable lives into a fascinating account of nuclear strategizing over the last five decades. This unfailingly compelling narrative is indispensable reading for all who would understand the desperate urgency of containing the menace of nuclear proliferation.”
— DAVID KENNEDY, PROFESSOR OF HISTORY EMERITUS, STANFORD UNIVERSITY

“This brilliant, penetrating study of nuclear threats is in the tradition of David Halberstam and Neil Sheehan. Taubman has, perhaps as importantly, unlocked the history of the war we never had. Readers will tremble at the dangers the world has faced and still faces today.”
— BOB WOODWARD

“A richly detailed account of one of the most important issues of our time, The Partnership should be on the bedside of every presidential candidate, national affairs journalist and engaged citizen.”
— TOM BROKAW

Contention and Trust in Cities and States explores cities and nation-states throughout history and around the world, bringing together the research of top scholars. It takes as a jumping-off point the work of the late Charles Tilly, but proceeds varied topics ranging from how today’s drug cartels undermine nation-states to how cities, nation-states, and empires treated religious minorities in the middle of the last millennium. Threaded throughout are themes of city-state relations, trust networks and commitment, democracy and inequality, and the importance of historical legacies in shaping state structures, practices, and capacities.

Charles Perrow is famous worldwide for his ideas about normal accidents, the notion that multiple and unexpected failures--catastrophes waiting to happen--are built into our society's complex systems. In The Next Catastrophe, he offers crucial insights into how to make us safer, proposing a bold new way of thinking about disaster preparedness.

Perrow argues that rather than laying exclusive emphasis on protecting targets, we should reduce their size to minimize damage and diminish their attractiveness to terrorists. He focuses on three causes of disaster--natural, organizational, and deliberate--and shows that our best hope lies in the deconcentration of high-risk populations, corporate power, and critical infrastructures such as electric energy, computer systems, and the chemical and food industries. Perrow reveals how the threat of catastrophe is on the rise, whether from terrorism, natural disasters, or industrial accidents. Along the way, he gives us the first comprehensive history of FEMA and the Department of Homeland Security and examines why these agencies are so ill equipped to protect us.

The Next Catastrophe is a penetrating reassessment of the very real dangers we face today and what we must do to confront them. Written in a highly accessible style by a renowned systems-behavior expert, this book is essential reading for the twenty-first century. The events of September 11 and Hurricane Katrina--and the devastating human toll they wrought--were only the beginning. When the next big disaster comes, will we be ready?

The supercommittee's failure to reach an agreement on debt reduction will probably result in unexpected reductions of the U.S. nuclear arsenal. That possibility concerns the defense establishment, but it also presents an opportunity: It might finally be possible to have an honest debate about the role of nuclear weapons in U.S. strategy and the prospect for further arms reductions.

Before moving ahead with this conversation, though, it is critical to review and debunk three misguided ideas about nuclear weapons.

The first is that our nuclear world is safe and stable and that all we need to do now is prevent other nations from acquiring nuclear weapons. Though it is undoubtedly true that the U.S. stockpile is safer than ever, the dangers are far from over. Nuclear terrorism remains a threat. Mistakes are possible, too. In just one example, in August 2007, six nuclear warheads disappeared for two days between North Dakota's Minot and Louisiana's Barksdale Air Force bases.

What's more, unsafe nuclear weapons elsewhere remain a major threat. Tensions between nuclear India and Pakistan, the security of the Pakistani nuclear arsenal and the future of the North Korean nuclear weapons program all suggest that the commitment to making U.S. weapons more reliable and secure will not solve the problem.

The second piece of nuclear mythology is that nuclear disarmament has never taken place and never will. Put slightly differently, it is the idea that nuclear history is proliferation history. But nuclear disarmament is far from unprecedented. South Africa, Ukraine, Belarus and Kazakhstan all disarmed. Many nuclear-capable states chose to pursue security without nuclear weapons because policymakers recognized these weapons would endanger rather than protect them. Sweden went down the nuclear path and then decided against it in the late 1960s.

Germany had a nuclear weapons program during World War II but became a law-abiding, non-nuclear member of the Non-Proliferation Treaty. Japan had two nuclear weapons programs during the war and accumulated a significant quantity of plutonium; since then, its authorities thought about restarting a weapons program four times but decided against it.

In each of those cases, most analysts did not believe that giving up nuclear weapons ambitions was possible. They were wrong, and today we all are glad these countries chose the path they did.

The third misguided concept is that reducing the size of the U.S. nuclear arsenal will lead to proliferation. Those who believe this think that countries that no longer feel protected by U.S. nuclear weapons will start building their own to protect themselves. Although this might have some validity, it should be assessed on a case-by-case basis.

Historically, many of the states that have disarmed or given up their nuclear-weapon ambitions - including every non-nuclear nation outside of NATO - have done so despite the absence of a nuclear-security guarantee.

On the other hand, states determined to get the bomb, such as the United Kingdom and France, have done so despite security guarantees. Finally, this argument assumes that the role of nuclear weapons in future alliances and geopolitical relationships will be as important as it was in the past. This might be true, but it cannot be considered a fact. It is just a bet on the future and a set of policy priorities.

In 2007, "the four horsemen" - Henry Kissinger, Sam Nunn, William Perry and George Shultz - wrote a highly influential opinion piece in the Wall Street Journal arguing that relying on nuclear weapons for the purpose of deterrence has become "increasingly hazardous and decreasingly effective." Coming from former Cold Warriors from both sides of the political aisle, it legitimized the goal of a world without nuclear weapons and challenged the conventional wisdom.

Now policymakers in Washington and candidates on the electoral trail should embrace the issue, and begin a real conversation with the electorate about the role of nuclear weapons in U.S. policy rather than allowing that policy to be driven by inertia or budget cuts.
