“It wasn’t an easy decision,” an Iranian official source said when asked about Russia’s intervention in Syria. “The Russians were certain that if they did not move now, the next war they would fight would be inside their borders; this is about Russia’s national security before being about Syria. Therefore, a decision to start this pre-emptive war was taken by the Kremlin.”

For decades, Syria has been one of Russia’s main allies in the Middle East. The collapse of the Soviet Union didn’t change anything in this regard. Moscow continued to support Damascus with whatever necessary to keep the old empire’s last balcony on the warm waters of the Mediterranean Sea.

In 2011, amid the eruption of the revolution in Syria, the Russians started feeling the heat. It was almost obvious to them that the fall of the regime in Damascus would lead to serious changes in Russia’s status in the Middle East; thus this wasn’t an option to even think about, and everything possible should be done to maintain the regime and keep it breathing, should this be using the veto in the UN Security Council, sending arms and ammunitions, or as we are witnessing today, intervening militarily and fighting to keep the status quo. Russia is not the only ally of the Syrian government; Iran also has been supporting President Bashar al-Assad.

Russia and Iran have not previously been allies. They share common interests, common allies and common rivals; however, this doesn’t necessarily mean they act as allies. In Syria, their common interest has been — and still is — keeping their common ally, the regime, alive. Even within the Syrian regime, there are different views among the ranks on how to deal with both countries; there are officials who are seen as “Iranians” and others as “Russians.” This is prompted by fears among one wing that the Islamic Republic’s agenda in Syria involves Islamization of society, while the other wing that prefers the Iranians sees them as very reliable since they were the first to roll their sleeves up in the fight for the regime’s existence. Yet, this is only a matter of preferences, and nothing more.
