John McCain actually said...

When conditions on the ground have decisively begun to change for the better; that is when our troops should start to return home with honor...

I look forward to hearing what progress we're making on creating such a joint civil-military effort.

Will we withdraw our forces based on conditions on the ground or based on an arbitrary date, regardless of conditions on the ground?

It doesn't matter whether we call it a cliff or a ramp or anything else. It's still an exit sign.
