The Islamic State of Iraq and Syria (ISIS) used to have a different name: Al Qaeda in Iraq. After 2010 the group rebranded and refocused its efforts on Syria.

There are essentially three wars being waged in Syria: one between the government and the rebels, another between Iran and Saudi Arabia, and yet another between America and Russia. It is this third, neo-Cold War battle that made U.S. foreign policy makers decide to take the risk of arming Islamist rebels in Syria, because Syrian President, Bashar al-Assad, is a key Russian ally. Rather embarrassingly, many of these Syrian rebels have now turned out to be ISIS thugs, who are openly brandishing American-made M16 Assault rifles.

America’s Middle East policy revolves around oil and Israel. The invasion of Iraq has partially satisfied Washington’s thirst for oil, but ongoing air strikes in Syria and economic sanctions on Iran have everything to do with Israel. The goal is to deprive Israel’s neighboring enemies, Lebanon’s Hezbollah and Palestine’s Hamas, of crucial Syrian and Iranian support.

ISIS is not merely an instrument of terror used by America to topple the Syrian government; it is also used to put pressure on Iran.
