Well that's a polite way of putting it. He's in a cleft stick situation, is another way of putting it.
He's sent 3,000 US troops to their death in Iraq. So to justify all that bloodshed he has to (he thinks) keep sending in more troops. One more heave.
He's got nothing to lose. He won't get shot. He isn't standing for election again.
Unfortunately it won't work.
So he will just get the USA stuck deeper and deeper in the mire.
