I said it when Jimmy Carter did it, and I'll say it now:  former presidents and vice presidents should not attempt to conduct freelance foreign policy when they're out of office--particularly not presidents and vice presidents like Jimmy Carter and Dick Cheney, who are not generally regarded as having presided over America's finest hours, internationally speaking.  If Dick Cheney is so worried about Obama looking weak, he should maybe not try to undermine him.  Yes, Obama has occasionally been kind of a jerk about blaming his predecessors for everything from global financial meltdown, to regional blowfly infestations, to cold coffee at the White House mess.  I don't care.  A functioning foreign policy does not start with  public squabbling among the current and former high officers of the executive branch.
