Americans are opportunists. Once all hell broke loose, they inserted themselves into the fracas. But the initial dunderheaded moves were at least partially the responsibility of the EU. You can't pretend this was an American plan circa 1990.
You'll have to tell me why the Americans dithered, what they could have hoped to gain by dithering. In fact, many point to the Reagan-Neo/Con connections to Yugo defense structures as a reason why the US actually favored the Serbs in the 1980s.

On a previous occasion UpstateNY has given an account of American diplomatic actions in the Balkans, notably by James Rubin but also by others, so I am surprised that he would blame the EU. However the EU's lack of foreign policy and diplomatic coordination among member states made matters worse, especially in the early days of the war. We have met the enemy, and he is us — Pogo
I was only pointing out that EU diplomacy in the region always seems hasty, ill-considered, tendentious, and even arrogant.
The US was totally wrong on Kosovo. They were also bad on Bosnia but only from midway through to the end. Europe stumbled from 1990-1991 until the end of Bosnia.
