The Turkish incursion into northern Syria has revealed a central truth in international affairs: that the future of military interventions will not be Vietnam-style imbroglios or long wars of attrition. They will be mostly one-off cross-border incursions of limited lifespans, casualties, or attention (though, contrary to many recent cross-border operations, Turkey’s latest incursion has attracted a lot of attention). The terrain will be difficult and rural; the level of governance minimal.
President Donald Trump has upended American policy in Syria, and possibly in the entire Middle East, in one stroke. His unilateral decision to withdraw American troops from the Kurdish region of northern Syria, and thus give a green light for the Turkish invasion of the Kurdish enclave, has put all American goals in Syria in grave jeopardy. These included protecting the autonomous Kurdish enclave as a quid pro quo for the Kurdish militia’s singular military contribution in liquidating Islamic State and capturing its capital Raqqa at the cost of thousands of lives. They also included preventing the regime of Bashar al-Assad from reasserting control in northern Syria (a very important US objective in Syria was to circumscribe Russia’s and Iran’s reach and influence in the country). Finally, one of the principal aims of American policy in both Syria and Iraq has been to prevent the resurgence of the IS.
The nature of the conflict in Syria is changing shape again, with two important developments taking place over the past week. First, Turkey proposed cooperation with the United States in Afrin and Manbij, both of which are held by Syrian Kurds, whom the Turks consider hostile forces. Though no formal agreement has been reached, U.S. Secretary of Defense James Mattis said the U.S. would work with Turkey to coordinate their actions in Syria. Second, the Syrian Kurds appear to be willing to work with the Syrian regime against the Turkish assault on Afrin. Pro-regime forces reportedly entered Afrin on Feb. 20, a move that would require coordination with the Kurdish People’s Protection Units, or YPG, which controls the region.
