A big U.S. government weapons transfer to Iraq will no doubt be favored by the US military-industrial complex, which stands to profit further from the Iraq meltdown. This move will also be favored by those in Washington who realize how politically unpopular a third U.S. invasion of Iraq would be at home, but who want to "do something" in the face of the crisis. Shipping weapons may be an action short of war, but it usually leads to war. And as we have already seen in Iraq and Syria, very often these weapons fall into the hands of the al-Qaeda we are supposed to be fighting!
Because of the government's foolish policy of foreign interventionism, the U.S. is faced with two equally stupid choices: either pour in resources to prop up an Iraqi government that is a close ally with Iran, or throw our support in with al-Qaida in Iraq (as we have done in Syria). I say we must follow a third choice: ally with the American people and spend not one more dollar or one more life attempting to re-make the Middle East. Haven't we have already done enough damage?
