In battles, opponents exhibit positive illusions in both believing they can win. With great costs of failure and uncertain success, this represents extreme risk-taking behaviour. Conflict may be expected if one side is cornered, a sacrificial pawn in an overall war strategy, or demanded into action by politicians. However, in many cases even patently weaker forces fight despite nonviolent options. This is "military incompetence", a failure in the assessment of winning probability. Previous explanations (stupidity, psychological deviance and cognitive constraints) have been rejected. Recently, Wrangham [Evol. Hum. Behav. 20 (1999) 3.] proposed that such risk-taking could be adaptive through one of two effects: (1) Performance Enhancement through exaggerated resolve or (2) Opponent Deception by bluffing. Although adaptive if they confer a tendency to win, both processes promote risk-taking behaviour and are therefore potentially responsible for military incompetence. These hypotheses can be distinguished because the Performance Enhancement hypothesis predicts positive illusions in any type of conflict. In contrast, the Opponent Deception hypothesis predicts them in battles but not in surprise attacks, where lack of communication disables any bluff. We conducted a test of these hypotheses using data collected by the US Historical Evaluation Research Organisation, mainly from the Arab-Israeli and Second World Wars. The Opponent Deception hypothesis is supported over the Performance Enhancement hypothesis, but other explanations are not ruled out.

Why do some peace agreements successfully end civil wars, while others fail? What strategies are most effective in ensuring that warring parties comply with their treaty commitments? Of the various tasks involved in implementing peace agreements, which are the most important? These and related questions--life and death issues for millions of people today--are the subject of Ending Civil Wars.

Based on a study of every intrastate war settlement between 1980 and 1998 in which international actors played a key role, Ending Civil Wars is the most comprehensive, systematic study to date of the implementation of peace agreements--of what happens after the treaties are signed. Covering both broad strategies and specific tasks and presenting a wealth of rich case material, the authors find that failure most often is related not only to the inherent difficulty of a particular case, but also to the major powers' perception that they have no vital security interest in ending a civil war.

President George W. Bush has demonstrated impressive flexibility in reshaping his approach to foreign policy to deal with the new international challenges brought to the fore by the terrorist attacks.

Before Sept. 11, President Bush embraced a humble mission for the United States in the world. This country, he believed, had to "preserve the peace" by seeking to maintain the basic balance of power between nations. Now, Bush has abandoned the preservation of the old system. Instead, he seeks to change it by promoting liberty, freedom and eventual democracy in countries ruled by autocrats.

In doing so, Bush lines up next to "idealists" or "liberals" such as Ronald Reagan, Woodrow Wilson and Immanuel Kant, and implicitly distances himself from realists focused solely on the balance of power such as Richard Nixon, Thucydides and his own father, the 41st president.

In a second remarkable change, Bush has become a supporter, at least rhetorically, of nation building. Before Sept. 11, the Bush administration derided nation building as a Clinton-era distraction from the more important issues in international politics. Now, Bush has clearly identified the connection between rebuilding the failed state of Afghanistan and American national security interests. If Congress approves his proposals, Bush will be the author of the greatest increase in the American foreign aid budget since John F. Kennedy's presidency.

Third, the Bush administration before Sept. 11 expressed disdain for multilateral institutions. But in his speech this month before the United Nations, Bush outlined an ambitious proposal for revitalizing the United Nations and American cooperation with this most important multilateral institution.

To be credible, President Bush needs to do more to demonstrate his commitment to the promotion of democracy, nation building and multilateralism. Bush must show that he wants to see political reform in Saudi Arabia as well as in Iraq. Words about promoting liberty ring hollow if they apply only to some people.

To show seriousness on nation building, Bush should press for increases in the peacekeeping forces in Afghanistan. Those working to rebuild Afghanistan unanimously complain that the lack of security throughout the country is the No. 1 impediment to their work.

To make credible his pledge to reinvigorate the United Nations and other multilateral institutions, the president should complement his pledge to enforce U.N. resolutions on Iraq with a rededication of American participation in other international regimes. Bush could start with the ratification of the United Nations Convention on the Elimination of All Forms of Discrimination Against Women, an agreement that American officials helped craft.

Because many are suspicious of the president's recent embrace of democracy promotion, nation building and multilateralism, he must demonstrate a sustained commitment to his new foreign policy strategy.

If Bush has shown a willingness to consider new ideas about foreign policy, his critics -- both at home and abroad -- have demonstrated amazing conservatism. In a reversal of positions, those most opposed to Bush's new approach to foreign policy now seek to "preserve the peace" by defending the status quo. The core flaw in this is the assumption that the old international system was working. It was not.

Before Sept. 11, the United Nations had failed to enforce its own resolutions on Iraq. If the "international community" cannot act to execute its will when dealing with such grave issues as the proliferation of weapons of mass destruction, then it has no credibility on anything.

The international community is ineffective in dealing with despotism, poverty and human rights violations because it seeks to preserve state sovereignty above all else. Fifty years ago, this was a progressive idea, which brought about the end of colonialism. Today, it is a regressive idea, which preserves the sovereignty of dictators who defy international law, denying the sovereignty of their people.

It is odd to hear the international community invoked so often as the defender of high ideals and then see representatives from Iraq in the U.N. General Assembly. Should the United States really be a member of the same organization that includes Saddam Hussein? Eventually, autocracy should go the way of slavery and colonialism as simply unacceptable.

To be effective, the international community and the United States need each other. U.N. Security Council resolutions can only be enforced if the United States helps to enforce them. The United Nations can only assist in the building of new states or prevent the destruction of vulnerable regimes if the United States participates, and vice-versa. The international community has no army and no economy, but even the mighty and rich United States can't afford to remake the world alone. For an effective partnership, change has to come from both sides.

China is India's largest and most important neighbor, and despite recent efforts at improving relations between the two countries, the over half-century-old border dispute remains unresolved. While the prospects of a Sino-Indian border war are remote, it is essential that India understand the security implications of the rapidly modernizing Chinese military. It is in this context that this paper attempts to assess the airpower balance and the growing strength of the People's Liberation Army Air Force (PLAAF). The paper argues that even if the pace of its modernization remains slow, the PLAAF will have decisively surpassed regional air forces in strength and capabilities by the end of the current decade.

Phadke is an active duty officer of the Indian Air Force, currently working as Senior Fellow at the Institute for Defence Studies & Analyses, New Delhi, India. He has held five command positions and many important staff appointments. He is a postgraduate in Defence Studies and has been working on airpower issues. His current interests include China's military modernization and India's national security.

As Mozambique enters its tenth year of peace following a brutal and destructive civil war, the signs of continued democratic transformation and pro-market economic reform appear rosy, at least at first glance. Donors and the international community have quietly lauded Joaquim Chissano's recent announcement that he is "not disposed" to seek a third term as president of this former Portuguese colony of 17 million on the southeast coast of Africa. Together with President Frederick Chiluba's similar announcement in Zambia a few months ago, it looks to many like an indication that these two African democracies are maturing and consolidating the gains that they have made in recent years.

Mozambique's continued place atop the list of the world's fastest-growing economies has been seen as another signal that commitment to the "Washington Consensus" will provide the funds required to bring infrastructure, schools, and health care to the rural majority. It is no wonder, then, that Mozambique finds itself highlighted as a success story for the United Nations in conflict-ridden Africa. Many credit Mozambique's remarkable transformation to the UN's efforts to sustain the drawn-out peace negotiations, demobilize more than 90,000 soldiers, rebuild a unified national army, and foster the rise of a legitimate, peaceful opposition. Donor investments continue to support Mozambique today, funding more than half of the government's annual budget.

On the ground in Mozambique, however, the continuation of this upward trajectory looks anything but guaranteed. The newspapers hint at trouble just beneath the surface: two major bank failures, the assassination of the country's most respected independent journalist, the continued depreciation of the currency, and stop-and-start talks between the Frente de Libertação de Moçambique (or Frelimo, as the ruling party is usually called) and its main political rival, the Resist^encia Nacional Moçambicana (Renamo), about how to share power at the local level. In November 2000, when police in the city of Montepuez killed demonstrators challenging the government's claim to have won that year's national elections, tensions nearly exploded into large-scale violence. ¹

The UN's work in Mozambique was unprecedented in scope, and the results have been dramatic. Two consecutive free elections and growth rates approaching 10 percent a year over the past decade cannot be ignored. Some might argue that the items of bad news cited above are merely "bumps on the road" toward lasting peace, as Mozambicans of all stripes learn to resolve problems through dialogue and democratic competition. But a deeper look at Mozambique's political and economic situation suggests a bleaker interpretation.

The truth is that a number of deep cleavages threaten the future of Mozambique's democratic transition. What are these fundamental divisions? And more importantly, how can the political system be reformed in order to prevent them from worsening or even erupting into renewed civil war? A search for answers should begin with some basic background on Mozambique and its troubled recent history.
