Among specialists in international relations, the terrorist attack that toppled the World Trade Center also shattered the optimism to which the end of the Cold War had given rise. History, it turned out, had not ended. Globalization, the Big Idea of the 1990s, wasn’t likely to provide an all-purpose remedy for the world’s ills. As for the much-touted “unipolar moment,” its defining feature turned out to be not peace and stability but the prospect of open-ended conflict. Contemptuous of allies and disdainful of international norms, the Bush administration seemingly went out of its way to alienate the rest of the world. In the eyes of more than a few informed observers, the United States became a rogue nation. To critics who excoriated the administration for its arrogance and warmongering, the future of the world order began to look bleak indeed.

In this upbeat and admirable if ultimately unsatisfying book, Timothy Garton Ash argues that such gloom is misplaced. The signs of the times call not for despair, he believes, but for the West to redouble its efforts to build a “Free World,” making available to all the blessings of peace, liberty, and prosperity. The opportunity to create such a global order is at hand, but fleeting: Fail to seize the opportunity now and it may be lost forever.

A prolific journalist and historian who teaches at Oxford University, Garton Ash builds his book around a series of immensely readable essays examining the predicament in which Great Britain, the United States, and continental Europe now find themselves. The result is far more nuanced than Robert Kagan’s caricature of a feisty American Mars and a played-out European Venus talking past each other. It is far more interesting and persuasive as well.

According to Garton Ash, nations on both sides of the Atlantic—not least his own Britain—are internally divided, poorly led, and mired in myth, jealousy, and old resentments. As a consequence, they are unable to grasp where their true interests lie. In fact, he emphasizes, the divisions currently besetting the Atlantic community are trivial in comparison with the values that its members hold in common. Quoting Freud, he dismisses the West’s intramural quarrels as the “narcissism of minor differences.” Instead of squabbling about Iraq, farm subsidies, or the death penalty, Europeans and Americans ought to return to their true calling—nurturing the creation of a Free World that by all rights ought to encompass the entire globe.

Assigning to Britain the pivotal role of patching up the transatlantic divide, Garton Ash calls for a massive collaborative effort to make good on the promise of liberalism. Through free trade, greatly ex­panded support for international development and human rights, and efforts to forestall the impending crisis of global warming, Garton Ash believes that the West can eliminate global poverty, foster the final triumph of democracy, and ensure that the planet remains inhabitable for future generations.

But don’t count on the likes of George W. Bush, Jacques Chirac, and Gerhard Schröd­er to take up this cause anytime soon. According to Garton Ash, “foreign policy is too important to be left to the politicians,” who often as not “don’t know what they’re doing.” Instead, he advocates a sort of transnational populism, summoning “the thousand million” inhabitants of the developed nations to unite behind a “well-informed, enlightened, strategic approach to the rest of the world”—and to do so now, before environmental damage becomes irreversible, and before shifts in demography and economic clout leave the West unable to influence the rising powers of the East and South.

It’s an appealing vision. Garton Ash’s confidence in the essential goodwill of Western peoples—his belief that, together, we can rise above our petty concerns and act for the common good—makes it an affecting one as well. Yet embedded in it is a fundamental and typically Western flaw. Garton Ash assumes that all humanity shares his own secular liberal aspirations. In effect, Garton Ash’s Free World offers the promise of a decent, perhaps even comfortable life devoid of transcendence. He consigns God to the margins. In reality, however, God still haunts the world. Indeed, many of those upon whom Garton Ash is most eager to confer the blessings of liberty are adamant that God remain at the center of their universe. Any strategy for enlarging the Free World that fails to take this uncomfortable fact into consideration is doomed to fail.
