I agree. Even if there should not be a timetable, "back off" is arrogant.

In that position, you should absolutely expect to be asked that question every time you step out there.

A response like that certainly does not build support for the war at home.

The same exact ground result as we currently have, but delivered by a leader who most people didn't think was a prick, would be wonders for support. But, you have a porcupine be the guy at the microphone, and, like or not, support wanes.
