The Democrats who voted to support the war and rationalized that vote by making false claims about Iraq's WMD programs - a minority of Democrats, but much over-represented in Democratic leadership councils - were responsible for allowing the Bush administration to get away with lying about Iraq's alleged threat.
Here on the tenth anniversary of the Iraq War, it is important to remember that it was not just those in the Bush White House who were responsible for the tragedy, but leading members of Congress as well, some of whom are now in senior positions in the Obama administration.
The 4,500 Americans killed, the far larger number permanently wounded, the hundreds of thousands of Iraqis killed and millions displaced, the trillion dollars of US taxpayers' money squandered (and the resulting cutbacks through sequestration), the continued costs of the war through veterans' benefits and interest on the national debt, and the anti-American extremism in reaction to the invasion and occupation which has spread throughout much of the world all could have been avoided if the Democratic-controlled Senate hadn't voted to authorize this illegal and unnecessary war and occupation.
