"No boots on the ground"

"When the president made his commitment to 'no boots on ground' ... obviously that had to do with entering into the fray between the Qaddafi forces and the Libyan freedom fighters, and that's not what these guys are engaged in."

Which is no doubt true. That's what the pilots and the drone operators are for.
