Tony Judt in the New York Review of Books:
Those of us who opposed America’s invasion of Iraq from the outset can take no comfort from its catastrophic consequences. On the contrary: we should now be asking ourselves some decidedly uncomfortable questions. The first concerns the propriety of “preventive” military intervention. If the Iraq war is wrong—”the wrong war at the wrong time” —why, then, was the 1999 US-led war on Serbia right? That war, after all, also lacked the imprimatur of UN Security Council approval. It too was an unauthorized and uninvited attack on a sovereign state—undertaken on “preventive” grounds—that caused many civilian casualties and aroused bitter resentment against the Americans who carried it out.
The apparent difference—and the reason so many of us cheered when the US and its allies went into Kosovo —was that Slobodan Milosevic had begun a campaign against the Albanian majority of Serbia’s Kosovo province that had all the hallmarks of a prelude to genocide. So not only was the US on the right side but it was intervening in real time—its actions might actually prevent a major crime. With the shameful memory of Bosnia and Rwanda in the very recent past, the likely consequences of inaction seemed obvious and far outweighed the risks of intervention. Today the Bush administration—lacking “weapons of mass destruction” to justify its rush to arms—offers “bringing freedom to Iraq” almost as an afterthought. But saving the Kosovar Albanians was what the 1999 war was all about from the start.
And yet it isn’t so simple.
