“You know the irony is, he’s campaigning on the basis that he’s a success as a foreign policy president,” said Bolton, who announced he would endorse Romney earlier this week, of President Obama. “It’s just really amazing and you ask, what is it that made the success? And it’s because Navy SEAL Team 6 killed Osama bin Laden. That’s his definition of success.”

“As somebody pointed out, in 1969 when Americans landed on the moon, it’s like Richard Nixon taking credit for that, because it happened to occur during his presidency,” said Bolton, who spoke alongside Romney, S.C. Gov. Nikki Haley and Sen. John McCain in a ballroom at a Hilton resort. “The fact of the matter is this president has been a failure across the board in foreign policy and it’s jeopardized the United States in critical ways.”

Bolton called Obama the “first president, Republican or Democrat, at least since Franklin Roosevelt, who didn’t get up every morning thinking first about what threats the United States faces.”
