If Obama's incoherence and naiveté caused him to completely fail in the USA's foreign relations in the Middle East, and explicitly retreat, then Iran, Turkey and Russia will obviously fill the void, while Arab dictatorships implode.

Iran is no doubt emboldened, and that's not good news for the entire world, except for Khamenei, Nasrallah, Meshaal and the other Iranian proxies.
