As a high-profile Democrat Hillary might have helped avert the war if she had worked against it. Instead she jumped on board with it. She is 100% responsible for the choice she made. And what motivated it? It wasn’t an assessment of the facts. So what was it? Why have the Clintons always supported war? Every damn war, no matter how pointless or stupid?
