Considering that John McCain has never met a war he didn't like, he was just asking for it when he insulted former President Jimmy Carter:

Carter had harsh words for U.S. Sen. John McCain, R-Ariz. Farrow asked Carter how he felt about McCain’s stab earlier this year at Carter’s foreign policy record. In a televised comment, McCain said, “I thought Jimmy Carter was bad. It pales in comparison to this president.’’

But the 39th president didn’t flinch.

“That’s a compliment to me coming from a warmonger,” he said.

Ha, ha! Ya burnt!
