Iraqi security forces lost 2,300 Humvee armored vehicles when Islamic State overran the northern city of Mosul in June 2014. Coupled with previous losses of American weapons, the conclusion is simple: The United States is effectively supplying Islamic State with tools of war the militant group cannot otherwise hope to acquire. Losses to Islamic State include at least 40 M1A1 main battle tanks ... 74,000 machine guns, and as many as 52 M198 howitzer mobile gun systems. To help replenish Iraq's motor pool, the U.S. State Department last year approved a sale to Iraq of 1,000 Humvees, along with their armor upgrades, machine guns and grenade launchers. The United States previously donated 250 Mine Resistant Armored Personnel carriers (MRAPs) to Iraq, plus unaccountable amounts of material left behind when American forces departed in 2011. The United States is currently in the process of moving to Iraq 175 M1A1 Abrams main battle tanks, 55,000 rounds of main tank-gun ammunition, $600 million in howitzers and trucks, $700 million worth of Hellfire missiles and 2,000 AT-4 rockets. The Hellfires and AT-4's, anti-tank weapons, are presumably going to be used to help destroy the American armor in the hands of Islamic State. It's a surreal state of affairs in which American weaponry is being sent into Iraq to destroy American weaponry previously sent into Iraq.
