You'd be amazed at the amount of people who have assumed that, but the answer is no.
Bullet the Blue Sky was mainly against the US military and its involvement in the communist rule in El Salvador and Nicaragua from the former USSR. And yeah, he has definitely talked shit about the US and other countries telling them what they should do in order "to make poverty history" - hence, making himself a hypocrite.
But he's definitely not anti-American, he has a luxury apartment in Manhattan along with lifetime American friendships. His money has mainly come from the US fans after all...
