That sure sounded like a slam on Bush II. Did Eastwood forget that it was a Republican President who took us into Afghanistan and oversaw most of the length of the operations there? If one were going to make a dig against the wisdom of going into Afghanistan, the only administration that can reasonably be a dig against is the Bush II administration.
"But we did it ..." Yes, Republicans did that.
While perhaps it could have been handled differently, there were valid reasons for going into Afghanistan despite the way it turned out for Russia. Going after Al Qaeda at their training camps was one of W's more reasonable actions, something which can't be said for the Iraq diversion. But whether one finds it wisdom or folly, going into Afghanistan was most certainly on the plate of Bush II.
