For the Republican high command this is not just a cynical exercise in coalition building. It believes that America is mired in moral decay, and that the character of the nation must be rebuilt, which begins with improving the virtues of individual Americans by celebrating patriotism and religion. Thus there are prayers before Bush Cabinet meetings. Thus routine meeting by interest groups with the administration are punctuated by calls to praise God and the Bible. And thus one of the great benefits of the war with Iraq; it has made patriotism even more pervasive — helping to remoralize the nation around individualism and self-reliance, banishing to the sidelines the role of the social and the commonwealth in supporting good character. Gerrymander and alliance with Pentecostals alike serve the great cause.

American liberals feel their country is being taken from them and rage in impotent fury. It is impossible to underestimate, they say, how Sept. 11 has changed the rules of the political game. Security has become the Republicans trump card, and under its cloak the country is being driven unassailably to the right. This generation of Republicans respect neither the letter of the constitution nor its custom or practice. What they want is an entrenchment of their power and their own idiosyncratic world view — whether prioritizing tax cuts to enrich the “investor class” and so boost Wall Street, or insisting that pre-emptive unilateralism must rule in the name of homeland security. The troika deemed to be in their way — the United Nations, France and the New York Times — are mocked and savaged.

It is such a seismic change in America’s political geography, yoking ancient visceral feelings about American exceptionalism with contemporary conservatism, that a growing group of liberal intellectuals believe that not even a Democrat President in 2004 could move the country back to any multilateralist international framework.

Professor Charles Kupchan, a member of the Council of Foreign Relations and part of the task force set up to examine how trans-Atlantic relations could be improved is pessimistic. In a well-regarded book, The End of the American Era, he argues that America is set on a path of economic, political and military isolationism. Over the next decade the paths of the EU and US will diverge — whoever runs the US. The trends are too deep-seated to overturn.

The diplomatic and economic events of the past six weeks, he thinks, are but a down payment on what is to come. America, in allowing the dollar to fall freely and the euro to rise, is knowingly and carelessly exporting deflation to Europe — so EU recession and falling prices are becoming a racing certainty. The two sides are squaring up to each other over trade, with the EU insisting that the US remove its export tax rebates and US insisting that Europe lifts restrictions on the import of GM crops — and neither is giving ground. The differences over the role of the UN in Iraq remain profound. Never before have trends in the two continents diverged so fundamentally.

It is all incredibly dangerous — an undermining of how the globe is governed with nothing to put in its place. Globalization itself could be in peril. Yet debate in Britain, rather like pre-war appeasement, is fundamentally misinformed. The right-wing press fulminates against the consolidation of Europe without recognizing how the world is changing. That doesn’t mean the choices are easy. For the UK to adopt the euro by entering the euro zone as it becomes an area of falling prices is much less tempting; but to be outside the EU bloc politically is suicidal — the cause of the tension between Tony Blair and his finance minister, Gordon Brown.

Equally Blair’s hope of sustaining a unipolar world of Europe and America united looks like crying for the moon. American conservatism is creating a universe of invidious choices.
