We have gone to war to defend Muslim interests, specifically in Kosovo and former Yugoslavia. We have defended them in Desert Shield/Desert Storm. We have aided them against the Soviet Union in Afghanistan. And none of that has done anything.
If it hasn't done anything why do it in the first place?
Because it served our own interests at the time. In Afghanistan it was a proxy war against our enemy the Soviet Union. In Desert Storm it was to roll back the regime of Saddam Hussein and guarantee stability. In Kosova it was...hmmm. I don't know on that one. The Libs were screaming to "do something" and the Euro's were busy sitting around and fapping, as usual, so Clinton decided to go this route.
