4,000 Americans killed in Iraq

Last we saw the 5th Anniversary of the war in Iraq. Today news broke that we have also lost 4,000 Americans to this unjust, un-American, and irresponsible war.

In honor of the fallen The Huffington Post's Nico Pitney has put together a mosaic of "the 4,000 brave men and women who sacrificed everything for us -- and the two men who would continue this great tragedy, despite the cost to our soldiers, our military, and our nation."

Please note that since some photos of fallen U.S. soldiers are unavailable, there are duplicates.
