Two things: we didn't invade the former Yugo, and the US was not acting unilaterally. Scream from the hilltops about the audacity of the UN (not to mention McCain and Clinton), I'm with you brother. But the US is the greatest nation this earth has ever seen, and not only to its own citizens.
But we bombed the crap out of it, and we were helping to speed up the Euro inspired Yugo disintegration. We should have acted unilaterally and left them alone.
