The situation in the region is unprecedented. For the first time since the World Wars, virtually every country from Libya to Afghanistan is involved in a military conflict. (Oman seems to be the exception.) The degree of chaos, uncertainty, and complexity among the twisted and often contradictory alliances and enmities is mind-boggling. America and its allies are fighting alongside Iran to combat the Islamic State (IS) in Iraq and Syria but in Yemen, the United States and many of those same regional partners are collaborating to push back Iranian-backed Houthi forces. Israel and Saudi Arabia are closely aligned in their concerns about Iran while historical divisions between the two remain great. Iran supports Bashar al-Assad in Syria; the United States and Western allies deplore his policies but tolerate his presence while some of the rebel forces we are supporting in the fight against the Islamic State in that country seek his (long overdue) removal.
