Gates on his VP Biden denunciation (“in the wrong on nearly every major foreign policy and national security issue over the past four decades.”) He actually agreed with Biden on foreign policy during the Obama administration, and apparently that statement was all about various times Biden opposed GOP legislation dating back to at least the Reagan administration:

Gates also stood by his withering criticism of Vice President Joe Biden, who he writes has been “in the wrong on nearly every major foreign policy and national security issue over the past four decades.”

Asked to name specifically what Biden had gotten wrong, Gates ticked off a litany of what he termed errors in judgment, including Biden’s vote against a bill granting aid to Vietnam in the aftermath of the war when Biden had first joined the Senate. He also criticized Biden’s opposition to several Reagan administration defense bills as well as to the first Gulf War.

Yet Gates also described Biden as a “stand-up guy” and acknowledged they had agreed on “almost every major foreign policy question that came before the Obama administration.”

And from his CBS book promotion interview, there was this anecdote:

“One time when I agreed with him on something — often Admiral Mullen, the Chairman of the Joint Chiefs, and I would ride back to the Pentagon together from the White House — and Mullen turned to me at one point [and] said, ‘You know that you agreed with the vice president this morning.’ And I said, ‘Yeah, that’s why I’m rethinking my position.’”
