He just flip flopped on Iraq today so he is in trouble.
From NewsBusters.org:
BARACK OBAMA CLIP #1, DATED MAY 18: Iran, Cuba, Venezuela, these countries are tiny compared to the Soviet Union. They don't pose a serious threat to us.
OBAMA CLIP #2, DATED MAY 18: Iran, they spend 1/100th of what we spend on the military. I mean, if Iran ever tried to pose a serious threat to us, they wouldn't stand a chance.
OBAMA CLIP #3, DATED MAY 20: Iran is a grave threat. It has an illicit nuclear program. It supports terrorism across the regions and militias in Iraq. It threatens Israel's existence. It denies the Holocaust.
