The Middle East will be a contest for influence and power between Saudi Arabia and Iran. The US may play a surprisingly small role. From Peter Van Buren at antiwar.com:
Islamic State is in fatal decline. The Middle East will soon enter a new era, post-Islamic State, dominated by the Saudi-Iranian power struggle. The struggle will, as it has as it ran alongside the fight against Islamic State, involve shifting Sunni and Shiite allegiances. But the fight is not about religion. Religion this time has more to do with complicating choices in political bedfellows and where proxies are recruited than dogma. For behind that Sunni-Shiite curtain, this is a classic geopolitical power struggle – for control of Iraq and Syria, and for expanding diplomatic and strategic reach throughout the region.
In the fight against Islamic State, it has been all too easy to cite expediency in putting complex issues aside, but as the alliances created for that struggle run their course, the new reality will force changes. With the strategic value of funding Islamic State as a bulwark against Iranian influence in Iraq gone, the Saudis appear to be pivoting toward building warmer relations with the Shiite government in Baghdad. That a Saudi airline is just now announcingthe first return of direct service between the two countries since Saddam Hussein invaded Kuwait in 1990 is no coincidence, nor is it an isolated event
The Saudis also appear willing to let a lot of religious water pass under the bridge to take advantage of a looming intra-Shiite power struggle in Baghdad among Prime Minister Haider al-Abadi, former Prime Minister Nouri al-Maliki (above), and Shiite cleric Muqtada al-Sadr. Sadr, the most religiously zealous Shiite of the group, has always been something of a nationalist, and unlike his rivals, is wary of Iranian influence. It is perhaps not surprising that he has made friendly trips to Sunni Riyadh and the United Arab Emirates, the first time in 11 years done under official invitation from Saudi Arabia.
