WSJ Opinion: Does Obama Understand Defeat?

Some guy named Bret Stephens from the WSJ editorial board wrote something that I have been thinking for a long time:

"But here are questions for Mr. Obama: Could there be something worse than the indefinite maintenance of a flawed policy? [Referring to John McCain's 100 years in Iraq policy] What if, following a U.S. withdrawal, Iraq collapsed into chaos? What if U.S. embassy personnel have to be helicoptered to safety from the roof of the Baghdad embassy? It's not as if this hasn't happened before."

and then he concludes with:

"In his speech, Mr. Obama noted that there was no point trying to best Mr. McCain in matters of experience, that what counted was good judgment. Very true. How one can have the latter without the former is a question for the rest of us to consider."

That's a good question. Also, how is he going to get national accord in Iraq? He says that needs to be done so the American troops can leave but how will it be done??
