While all of the 2016 candidates declare their strategies for victory against ISIS, President Obama’s leading from behind has now entered the Middle East and the West into a free-for-all that cannot end any way but poorly.

The best way to understand the situation in Syria is to look at the situation and motivation of the various players. All of them have varying agendas; all of them have different preferred outcomes. Few of them are on anything approaching the same page. And Barack Obama’s failure of leadership means that there is no global power around which to center.

ISIS. ISIS has gained tremendous strength since Barack Obama’s entry to power and pullout from Iraq. They currently control northern Syria, bordering Turkey, as well as large portions of northern Iraq. Their goal: to consolidate their territorial stranglehold, and to demonstrate to their followers that they, and not other competing terrorist groups like Al Qaeda, represent the new Islamic wave. They have little interest in toppling Syrian dictator Bashar Assad for the moment. They do serve as a regional counterweight to the increasingly powerful Iranians – increasingly powerful because of President Obama’s big nuclear deal, as well as his complete abdication of responsibility in Iraq.

Assad. The growth of ISIS has allowed Assad to play the wronged victim. While the FSA could provide a possible replacement for him, ISIS can’t credibly do so on the international stage. Assad knows that, and thus has little interest in completely ousting them. His main interest is in continuing to devastate the remaining FSA while pretending to fight ISIS.

Egypt/Saudi Arabia/Jordan. As you can see, ISIS, Iran, and Assad all have one shared interest: the continued existence of ISIS. The same is not true with regard to Egypt, Saudi Arabia, and Jordan, all of whom fear the rise of radical Sunni terrorist groups in their home countries. They are stuck between a rock and a hard place, however, because openly destroying ISIS on behalf of Alaouite Assad, they embolden the Shia, their enemies. Egypt, Saudi Arabia, and Jordan would all join an anti-ISIS coalition in the same way they did against Saddam Hussein in 1991, but just like Hussein in 1991, they won’t do it if there are no Sunni alternatives available. Tunisia, Saudi Arabia, and Jordan are the top three sources of foreign fighters for ISIS.

Turkey. The Turks have several goals: to stop the Syrian exodus across their borders, to prevent the rise of the Iranians, and to stop the rise of the Kurds. None of these goals involves the destruction of ISIS. Turkey is Sunni; so is ISIS. ISIS provides a regional counterweight against Iran, so long as it remains viable. It also keeps the Kurds occupied in northern Iraq, preventing any threat of Kurdish consolidation across the Iraq-Turkey border. They will accept Syrian refugees so long as those other two goals remain primary – and they’ll certainly do it if they can ship a hefty portion of those refugees into Europe and off their hands.

Russia. Russia wants to consolidate its power in the Middle East. It has done so by wooing all the players to fight against one another. Russia’s involvement in the Middle East now looks a good deal like American involvement circa the Iran-Iraq War: they’re playing both sides. Russia is building nuclear reactors in Egypt, Jordan, Turkey and Iran. They’re Bashar Assad’s air force against both the FSA and ISIS. Russia’s Vladimir Putin doesn’t have a problem with destroying ISIS so long as doing so achieves his other goal: putting everyone else in his debt. He has a secondary goal he thought he could chiefly pursue in Eastern Europe, and attempted with Ukraine: he wants to split apart the North Atlantic Treaty Organization, which he rightly sees as a counterbalance to check Russian aggression. Thanks to today’s Turkish attack on a Russian plane, and thanks to the West’s hands-off policy with regard to the conflict, Putin could theoretically use his war against ISIS as cover to bombard Turkish military targets, daring the West to get involved against him. Were he to do so, he’d set the precedent that NATO is no longer functional. Two birds, one war.

All of which means that the only country capable of filling the vacuum would be the United States. Just as in 1991, a major Sunni power is on the move against American interests – but unlike in 1991, no viable option existed for leaving the current regime in power. And the US’ insistence upon the help of ground allies is far too vague. Who should those allies be, occupying ISIS-free ISISland?
