He was for them before he was against them or something.

Vice President Joe Biden accused Rep. Paul Ryan of putting two wars on the “credit card,” and then suggested he voted against the wars in Afghanistan and Iraq. […]

“I was there, I voted against them,” Biden continued. “I said, no, we can’t afford that.”

Then Sen. Biden voted for the Afghanistan resolution on Sept. 14, 2001 which authorized “the use of United States Armed Forces against those responsible for the recent attacks launched against the United States.”

And on Oct. 11, 2002, Biden voted for a resolution authorizing unilateral military action in Iraq, according to the Washington Post.
