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.

For centuries, dictators ruled Russia. Tsars and Communist Party chiefs were in charge for so long some analysts claimed Russians had a cultural predisposition for authoritarian leaders. Yet, as a result of reforms initiated by Mikhail Gorbachev, new political institutions have emerged that now require election of political leaders and rule by constitutional procedures. Michael McFaul traces Russia's tumultuous political history from Gorbachev's rise to power in 1985 through the 1999 resignation of Boris Yeltsin in favor of Vladimir Putin.

McFaul divides his account of the post-Soviet country into three periods: the Gorbachev era (1985-1991), the First Russian Republic (1991-1993), and the Second Russian Republic (1993-present). The first two were, he believes, failures--failed institutional emergence or failed transitions to democracy. By contrast, new democratic institutions did emerge in the third era, though not the institutions of a liberal democracy. McFaul contends that any explanation for Russia's successes in shifting to democracy must also account for its failures. The Russian/Soviet case, he says, reveals the importance of forging social pacts; the efforts of Russian elites to form alliances failed, leading to two violent confrontations and a protracted transition from communism to democracy.

McFaul spent a great deal of time in Moscow in the 1990s and witnessed firsthand many of the events he describes. This experience, combined with frequent visits since and unparalleled access to senior Russian policymakers and politicians, has resulted in an astonishingly well-informed account. Russia's Unfinished Revolution is a comprehensive history of Russia during this crucial period.

Russia's first decade after the collapse of the Soviet Union has been simultaneously tumultuous and transformative. For most of the 1990s the Russian economy was in free fall, the legal system in absentia, and the majority of citizens engaged primarily in survival efforts. Not surprisingly, the former superpower also struggled to adapt to its greatly diminished means and status.

Russia after the Fall examines Russian politics, economics, society, and foreign and security policy. Internationally renowned experts provide retrospective analyses of how Russia has fared in its reform efforts and a prospective look at the challenges ahead. This book will be of interest to scholars, students, and a general audience seeking to better understand where Russia has been and where it is going.

The celebration in Prague should have been more raucous. The most successful alliance in world history has extended to corners of Europe unimaginable just a few years ago. The military capacity gained for the North Atlantic Treaty Organization from expansion is minimal but the political returns will be fantastic. More than any other institution, NATO has helped make Europe democratic, peaceful and whole. What is particularly striking about the new members -- Slovenia, Lithuania, Estonia, Latvia, Bulgaria, Romania and Slovakia -- is how many of them emerged from Communist rule with no democratic traditions. The pull of NATO, the desire to join this Western club, created real incentives for democratic consolidation.

Western democracies face increasing constraints on the use of their overwhelming military power. The classical logic, legitimacy and effectiveness of employing force to safeguard national interests apply less and less. State and non-state adversaries threaten important and even vital Western values and interests but are seemingly underterred by - or even inspired by - Western military superiority. At the same time, phenomena such as globalisation, the growing transparency of the battlefield and changing Western value systems subject civilian and military leaders to mounting pressure to wield military power selectively and to use increasing discrimination in choosing means as well as ends.
