ISIS looks like a coalition of old Al Qaeda in Mesopotamia survivors, Iraqi Ba’athists, and conservative Syrian Sunni rebels against the Assad government. If ISIS wins in western Iraq and eastern Syria and establishes a caliphate, what will happen to that coalition? Will the coalition hold together in happier times once external dangers are reduced? Or will “hunting season” open as the members pursue disparate goals?
If you look at this over the long-run, working to strengthen good governance and economic development around the world is a good idea. The Islamist movements and the refugees seeking to break into Europe (and the US for that matter) are fleeing stagnant economies, misgovernment, and often violence. “An ounce of prevention is worth a pound of cure.” Alas, I’m not sure that we know how to do this—aside from empires.
The Iraq War was a disaster. As a result, Americans don’t want another real war at the moment. It would take a real war to slow down Iran’s pursuit of nuclear weapons by any significant amount of time. It would take conquest and occupation to stop it entirely. So, the odds are that President Obama’s pursuit of an agreement with Iran to delay that country’s acquisition of nuclear weapons by some indefinite, but shorter, period is about the best that we can hope for.
However, confessing that we don’t want to do anything serious about Iran estranges us from Israel and Saudi Arabia. A nuclear Iran appears to both Israel and Saudi Arabia as a grave security threat. One of these days, the two countries may decide that Allah/Yahwey helps those who help themselves. Perhaps the key decisions will be made in Jerusalem. Israel and Saudi Arabia have a community of interest in doing something about Iran’s nuclear program. The Saudis probably could not manage a pre-emptive attack on their own. The Saudis probably could not manage to fend-off an angry American reaction on their own. In both cases, a tacit alliance with Israel would be very valuable. On the other hand, Israel and Iran have a community of interest in doing something about ISIS, while Saudi Arabia has not made much of an effort against ISIS because it is beating up on Iranian clients in Iraq and Syria. It is difficult to imagine Israel working a deal with Iran over ISIS if it meant tolerating Iranian pursuit of nuclear weapons. It is easier to imagine Saudi Arabia turning on ISIS as part of a deal with Israel. The thing all the decision-makers—in Riyadh, Jerusalem, Tehran, and Washington—are bearing in mind is that any attack on Iran’s nuclear program will start a bigger war in the Middle East, rather than end the current ones. So, perhaps cooler heads will prevail. Perhaps there will be a grand bargain instead of Armageddon. An American presidential campaign in which a host of Republican hopefuls appear to have been recruited from clown college and the anointed Democratic candidate once voted for the Iraq War just to appear tough enough to be president doesn’t inspire confidence.

 It appears that the long drop in homicide rates in most American cities has been problematic for local television news stations. Perhaps they should just keep news crews in some place like South Sudan.
 In a few years, someone is going to add a chapter to one of those What If? books that explores “counter-factual history.” My own version runs something like the following. Saddam Hussein was 66 when he was overthrown by the coalition of “the all-too-willing”; he had a bad back, but was afraid to have surgery because it would involve general anesthetic and something might happen; his sons were violent morons who were unlikely to be able to either share or hold power after the eventual death of their father; Iraq had attacked Iran in 1980 and the Iranians were—and are—eager for pay-back; the Shi’ite majority and the Kurds were eager to chart their own course, if only the Sunni minority would get their boot off the necks of the vast majority of Iraqis; and Abu Musab al-Zarqawi, the founder of Al Qaeda in Mesopotamia (the ancestor of ISIS) was operating in Syria from about 2002. So, even without the invasion, things might have shaken-out pretty much as they did. Only, we wouldn’t have our finger-prints all over the rubble. See: Richard K. Betts and Samuel P. Huntington, “Dead Dictators and Rioting Mobs: Does the Demise of Authoritarian Rulers Lead to Political Instability?”, International Security, Vol. 10, #3 (Winter 1985-1986), pp. 112-146.
 Perhaps we could partition the place with Russia? See: http://en.wikipedia.org/wiki/Anglo-Soviet_invasion_of_Iran
 One of the ways to think about Saudi Arabian intervention in the Yemen civil war is as an opportunity to give their soldiers and flyers some combat experience before, you know…..
