It is time to stop pretending that Europeans and Americans share a common view of the world, or even that they occupy the same world. On the all-important question of power - the efficacy of power, the morality of power, the desirability of power - American and European perspectives are diverging. Europe is turning away from power, or to put it a little differently, it is moving beyond power into a self-contained world of laws and rules and transnational negotiation and cooperation. It is entering a post-historical paradise of peace and relative prosperity, the realization of Kant's "Perpetual Peace." The United States, meanwhile, remains mired in history, exercising power in the anarchic Hobbesian world where international laws and rules are unreliable and where true security and the defense and promotion of a liberal order still depend on the possession and use of military might. That is why on major strategic and international questions today, Americans are from Mars and Europeans are from Venus: They agree on little and understand one another less and less. And this state of affairs is not transitory - the product of one American election or one catastrophic event. The reasons for the transatlantic divide are deep, long in development, and likely to endure. When it comes to setting national priorities, determining threats, defining challenges, and fashioning and implementing foreign and defense policies, the United States and Europe have parted ways.

The United States, in short, solved the Kantian paradox for the Europeans. Kant had argued that the only solution to the immoral horrors of the Hobbesian world was the creation of a world government. But he also feared that the "state of universal peace" made possible by world government would be an even greater threat to human freedom than the Hobbesian international order, inasmuch as such a government, with its monopoly of power, would become "the most horrible despotism." How nations could achieve perpetual peace without destroying human freedom was a problem Kant could not solve. But for Europe the problem was solved by the United States. By providing security from outside, the United States has rendered it unnecessary for Europe's supranational government to provide it. Europeans did not need power to achieve peace and they do not need power to preserve it.

The current situation abounds in ironies. Europe's rejection of power politics, its devaluing of military force as a tool of international relations, have depended on the presence of American military forces on European soil. Europe's new Kantian order could flourish only under the umbrella of American power exercised according to the rules of the old Hobbesian order. American power made it possible for Europeans to believe that power was no longer important. And now, in the final irony, the fact that United States military power has solved the European problem, especially the "German problem," allows Europeans today to believe that American military power, and the "strategic culture" that has created and sustained it, are outmoded and dangerous.

Most Europeans do not see the great paradox: that their passage into post-history has depended on the United States not making the same passage. Because Europe has neither the will nor the ability to guard its own paradise and keep it from being overrun, spiritually as well as physically, by a world that has yet to accept the rule of "moral consciousness," it has become dependent on America's willingness to use its military might to deter or defeat those around the world who still believe in power politics.

We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness. That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed...

America is a strong nation, and honorable in the use of our strength. We exercise power without conquest, and we sacrifice for the liberty of strangers.

Americans are a free people, who know that freedom is the right of every person and the future of every nation. The liberty we prize is not America's gift to the world, it is God's gift to humanity.
