I was wondering how he was going to pull off the famous Obama split tonight.
He did it chronologically, and in two ways.
First, in the speech itself:
In the first part of his speech he sounded like Winston Churchill.
In the second part of his speech, he sounded like Lady Churchill.
Secondly, with regard to his course of action:
Commit troops for the Right, and then
Announce their withdrawal prematurely, in time for the 2012 election - for the Left.

It was clear for the world to see that we are without the most important ingredient for a chance of success: a determined president whose heart is in the effort.
