If he were to be president during 9/11, there is a good chance that he would not have taken military action.
Against Afghanistan? Bullsh**t. After the second tower was hit, everyone within the federal government knew that once Al Qaeda was established as the perpetrator, the Taliban would also go down. To say that Gore was some liberal pussy is nothing short of asinine. Gore was one of ten Democratic Senators to vote in favor of Operation Desert Storm, a much more controversial action (at the time) than Afghanistan in 2001. There's no way in hell Gore would have ignored the advice of the CSG, which I believe Clinton created.
