UPDATE: Looks like she meant "McKiernan," according to HuffPo's Jason Linkins:
The commanding general in Afghanistan didn't merely state that Surge tactics won't work! He also said that tribal involvement in the COIN strategy wouldn't work either! Absolutely right on infrastructure in Afghanistan though! Know what they really need in Afghanistan to enhance security? ROADS.
Palin thinks our commander in Afghanistan is someone named "McClellan." It is, I believe, McKiernan. And Palin is DEAD WRONG. He absolutely said that tribal involvement in Afghanistan COIN strategy would not work.
