"What should the United States do about ISIS now that they've taken over half of Syria and a third of Iraq?The answer is: let Assad, the Iranians, the Turks, and, yes, the Russians take care of it, since they are the states directly threatened by the growth of the so-called Islamic State. Why should we fight their war for them?Contrary to the War Party's hebephrenic appeals to intervene, inaction on our part is key to the destruction of ISIS. The Grand Caliph of the Islamic State would like nothing more than to be able to portray ISIS as the valiant opponent of a US reentry into the region. It would be a tremendous propaganda victory for them to be able to frame their cause in this context because the result would be a successful international recruiting drive that would fill the ranks of the Islamic State's army even as hundreds are killed by US drones and missile strikes."
