Washington, DC perpetuated and deepened its Balkan blunder a few years after the Bosnia intervention when it intervened in Kosovo. Civil strife in Serbia’s restless, predominantly Albanian province, simmered and then flared in the mid-and late-1990s. This time, Washington didn’t even make a gesture of deferring to the leading European states, but took the policy lead early on. Ultimately, the United States led a seventy-eight-day air war against Serbia, compelling Belgrade to relinquish control to a largely NATO occupation force operating under a fig-leaf resolution that the UN Security Council approved. Russia reluctantly acquiesced to that peacekeeping resolution, despite Moscow’s ties to Belgrade and Russian interests in the Balkans going back well into the nineteenth century.
