Did John McCain just put his foot in it?

Among the other developments reported in today AfPak Daily Brief from Foreign Policy come the report that John McCain (and his trusty Tonto Mini-Me Joe Lieberman) have endorsed, out loud, US drone strikes inside Pakistan.  OK, those strikes are indeed an open secret, but as the FP comments note, the US does not acknowledge them officially, and the Zardari government has repeatedly taken public issue with the Obama government about the US's continued flaunting of Pakistan's sovereignty with them.

For McCain to be so brazen about it may be another notch in his personal "straight-talk express" belt, but it's hardly to be chalked up as a shining moment for US public diplomacy.
