He was for the war before he was against the war:
"BILL MOYERS: President Bush's recent speech to the American Enterprise Institute, he said, let me quote it to you. "The danger posed by Saddam Hussein and his weapons cannot be ignored or wished away." You agree with that?
JOE WILSON: I agree with that. Sure.
BILL MOYERS: "The danger must be confronted." You agree with that? "We would hope that the Iraqi regime will meet the demands of the United Nations and disarm fully and peacefully. If it does not, we are prepared to disarm Iraq by force. Either way, this danger will be removed. The safety of the American people depends on ending this direct and growing threat." You agree with that?
JOE WILSON: I agree with that. Sure. The President goes on to say in that speech, as he did in the State of the Union Address, is we will liberate Iraq from a brutal dictator. All of which is true.
