George Clooney on the Iraq war when it started
You can’t beat your enemy anymore through wars; instead you create an entire generation of people revenge-seeking. These days it only matters who’s in charge. Right now that’s us – for a while, at least. Our opponents are going to resort to car bombs and suicide attacks because they have no other way to win. [. . .] I believe [Secretary of Defense Donald Rumsfeld] thinks this is a war that can be won, but there is no such thing anymore. We can’t beat anyone anymore. [George Clooney in 2003]
