Of course, while military operations are prone to tragic mistakes and institutional failures, our failure to end the war is a policy failure, not a military one. Two consequences of that failure are the lives lost and taxpayer dollars squandered. Specifically, 2,350 Americans have lost their lives in the war, and while estimates vary greatly, some mark the civilian death toll at over 31,000. As for tax dollars, some estimates put the cost of the war to taxpayers at $4 million — per hour. The National Priorities Project, an organization working to shed some much needed light on America's spending priorities, estimates that as of this writing, the U.S. has spent over $765 billion on the war.
