I think it's a bad idea to fight altruistic wars of liberation; no great nation in history EVER fought that way and survived. If we had gone in for oil (or some other form of material gain), I would have loved it. But we were constantly told that's not the case, and I was called unAmerican for suggesting it.
I also felt we were setting ourselves up for another long-term, no-end-in-sight occupation, in a region where the people didn't want us, and where the cultural divide was immense. So far, I'm right on that one. I felt that after the initial wave of celebration, we would be in for a long, drawn out guerilla conflict.
In short, it was Bill Clinton in the Balkans all over again, and I opposed it for the same reasons.
