April has been a month of vibrant Russian foreign policy activity in the Middle East. A number of Middle Eastern leaders visited Moscow; Russian diplomats held the second consultative meeting between representatives of the Syrian government and the Syrian opposition; Russian planes evacuated all Russian citizens from Yemen, as well as citizens other countries, including the United States and Europe; Russia took an active part in reaching an interim solution in the Iranian nuclear talks; and Russian diplomats have been working on draft resolutions at the UN Security Council.

Some of the Russian leadership's decisions turned out to be rather unexpected. These included President Vladimir Putin’s announcement that a ban on deliveries of S-300 anti-aircraft missile systems to Iran be lifted, causing a negative reaction from some influential global and regional players, especially Israel, with which Russia has recently been successfully developing multilateral cooperation. Significantly, when explaining this decision, Russian officials put forward both commercial and reputational arguments related to the suspension of the contract with Iran between 2007 and 2010, as well as political ones.

In particular, during his four-hour televised conversation with Russia’s citizens April 17, Putin declared, "In no way is this a threat to Israel. This is only a defensive weapon. Moreover, we believe that given the conditions that are unfolding in the region, especially in connection with the events in Yemen, the supply of such weapons functions as a deterrent." Foreign Minister Sergey Lavrov was even clearer: "For Iran to have a modern air defense system is very urgent today, especially considering the rising tensions in the region, including around Yemen."

It's wrong to suggest — as some Western analysts did — that behind this decision stands Moscow’s desire to torpedo the deal between six world powers and Iran: The systems won’t be delivered any time soon, and Iran won’t be in a position to put serious pressure on Russia in the oil and gas market for some time. It's significant, however, that in this case the concerns of Israeli leaders were not taken into account. I recall that in the recent past, Moscow canceled the delivery of analogous weapon systems to Syria because of Israeli objections, as Putin mentioned in his TV appearance.
