Yes, a good move on Barry's part. It will be interesting now the ball is in Congress' court to see if they do come back early or decide the "crisis" isn't really important enough ...

Meanwhile, Obama wins politically -- no matter how Congress votes he has cover to either stay out if Congress votes no, or to go ahead if they vote yes. The only way he loses is if they vote no and he goes in anyway (which would be really tough to justify given Cameron's response to the "no" vote in Parliament) ...

This could be a really positive step in the right direction after the Executive's generally playing fast-and-loose with war powers post-WWII ...
