Former Vice President Dick Cheney blasted President Obama as the weakest president of his lifetime on Wednesday, following the president’s speech defending his foreign policy approach at the West Point commencement ceremony.

“He is a very, very weak president,” Cheney said in an interview with Fox News. “Maybe the weakest — certainly in my lifetime.”

Cheney went on to say that during a recent trip to the Middle East, allies he had “dealt with all the way back to Desert Storm” expressed alarm at the president’s handling of foreign policy.

“They all are absolutely convinced that the American capacity to lead and influence in that part of the world has been dramatically reduced by this president,” Cheney said. “We’ve got a problem with weakness, and it’s centered right in the White House.”
