Russia does have different interests than Iran, he noted. Russia wants a “stable, secular, and strong” Syrian military and not an entrenchment of Iranian proxy forces there or in Lebanon or Iraq.
Russia is benefiting from U.S. sanctions on Iran, he stated, because the more limited Iran’s resources, the less capacity Iran has to sustain its influence in Syria. Sanctions also benefit Russian oil companies.
Mamedov tempered this by emphasizing that although there is divergence between Russian and Iranian objectives, it is not in Russia’s interest for Iran to be destabilized. A stable Iran is important for Russia not only in the Middle East but also in the Caucasus and Afghanistan.
He offered reassurances that Russia understands and respects Israel’s interests vis-a-vis Iran in Syria, though Israel’s shoot-down of a Russian military aircraft over Syrian airspace in September 2018 generated friction. Russia seems to have a clear interest in deescalating tensions between Iran and Israel. But if a full-scale military conflict breaks out between the two countries, Russia might “reconsider its response.”
According to Stephen Blank, professor of Russian national security at the U.S. Army War College from 1989-2013:
I do think [certain U.S. officials] are interested in overthrowing the government of Iran. I don’t believe U.S. officials actually want war with Iran but they may back Iran into a corner and then who knows what the Iranians might do. Iran might unleash strikes on Israel via Hezbollah and Hamas and attempt to open up a second front.
I think Russia will try to prevent Iran from attacking Israel because they don’t want to see Iran get into a war it will lose. What Russia will do is support Iran against the United States diplomatically, economically; there may be arms transfers, overt or covert, [including] air, air defense, short and intermediate-range missiles.
Blank wrote in an October 2017 analysis for the Jamestown Foundation, “Russia’s fundamental strategic interests lie in promoting Iranian-US hostility, not cooperation…. Iranian-American hostility precludes [U.S. security dominance of the Middle East] and permits Russia to exercise influence by supporting the maintenance of a system of controlled tension that benefits the Kremlin.”
