While Russian officials have vocally complained about the Donald Trump administration’s increasingly frequent strikes on government forces and pro-government paramilitaries in Syria, the Kremlin remains focused on cooperation with Washington and is unlikely to respond to US actions as long as that is the case. If the US administration’s objective is to establish greater credibility in Syria to deal with Moscow from a position of strength, as Trump and other US officials have said, it may be working, at least so far.

In addition to striking a Syrian air base with cruise missiles in April in what US officials called a punitive response to Syria’s use of chemical weapons, the United States conducted air attacks on pro-government troops in May and June. US officials described the latter actions as necessary to protect “coalition and partner forces” in At Tanf, near Syria’s border with Iraq.

In April, a Kremlin spokesperson said the cruise missile attack, a major departure from the Barack Obama administration’s restraint in confronting Syria’s government, was a “significant blow” to US-Russia relations. Moscow simultaneously — but temporarily — suspended an agreement on deconflicting US and Russian air operations in Syria. More recently, Foreign Minister Sergey Lavrov has refused to recognize US “deconfliction zones” in Syria and denounced the repeated airstrikes as violations of international law. Russian defense officials have referred to US assertions that pro-regime forces threatened American partners as “absurd.” Despite this, and notwithstanding Lavrov’s personal expression of concern to Secretary of State Rex Tillerson, American-Russian discussions of Syria seem to have continued largely undisturbed. In fact, US officials privately refer to this one as perhaps the only area in which continuous dialogue is taking place between the two countries.

Why is Moscow continuing efforts to work with the United States despite these strong public positions? According to Dmitry Suslov, a Russian expert on American foreign policy at Moscow’s Higher School of Economics and the Council on Foreign and Defense Policy (analogous to the US Council on Foreign Relations in representing the foreign policy establishment), Russia’s arguments about international law are mainly diplomatic, intended to win sympathy for Russian policy from others — including in Europe, where the Kremlin sees growing frustration with the Trump administration — and to deflect attention from US and Western charges that Russia has violated international law. As Suslov explained to Al-Monitor, “There is a full recognition that international law matters little for the Trump administration.”
