Here's what MSNBC's Chris Matthews had to say last night:

Somebody is responsible for this war. Is it the president, the politicians in Congress who voted to authorize the war, the military who saluted Bush three years ago when the war was popular who are now calling for Defense Secretary Rumsfeld's resignation, or it was cooked intelligence from the administration?

Of course, others may say that in the end it was Saddam Hussein who was "responsible for this war."
