It does not condemn the consequences of ethnic cleansing, it codifies them. In Dayton, the latter was sacrificed to the former. The Bosnian state that has survived, moreover, is a weak and inchoate state, with a mini-state of its enemies in its midst. Its high rhetoric notwithstanding, the United States has brokered a chilly, realpolitikal deal that enshrines the balance of power in the Balkans, the domination of the region by Serbia and Croatia. Slobodan Milosevic and Franjo Tudjman tried once to carve up Bosnia, and they partially succeeded.

Finally the United States returned to its senses, or more precisely, to its values and its interests, and demonstrated that it is the only power in the world that can put a stop to such crimes, which are not only a stain upon the West but also a threat to its stability. A major war in southern Europe, and the population of refugees that it has produced, is not strategically acceptable. And even more pressing is the moral argument for American action. In the siege of Sarajevo, it was pluralism, the American dispensation, that was besieged. There are enormities that we tolerate only at the risk of our philosophy.
