Defense Secretary Robert Gates is on a trip to Afghanistan, landing in Kabul this morning. Gen. David Petraeus greeted him at the airport and the two immediately engaged in the sort of lighthearted banter you'd expect from two of the country's top military men.

As overheard by Jake Tapper:

"Welcome back, sir," Petraeus said to Gates. This is Gates' 13th trip to Afghanistan as Secretary of Defense.

The two men began walking.

"You returning to normal, you gonna launch some attacks on Libya or something?" Petreaus joked to Gates.

"Yeah, exactly," Gates joked back.

This is just going to get John McCain's and Joe Lieberman's hopes up again.
