On 30 September 2015, Russia launched a military intervention in Syria after a request by the Damascus regime in its fight against the Syrian opposition, which proved to be the decisive factor in a civil war that Syrian President Bashar al-Assad was struggling to win. The intervention transformed Syria into a live training ground for tens of thousands of Russian soldiers, who used it to test hundreds of weapons. While the battlefield was won, Russia’s political and economic hopes for Syria have yet to transpire nine years later.
Although Russia successfully bombed anti-Assad forces, it could not restore the Syrian regime's legitimacy in the eyes of the world. Since then, its subsequent invasion of Ukraine has all but obliterated Moscow’s credibility.
In recent years, the Syrian conflict has moved from a boil to a simmer. Since 2019, the US presence has dwindled to a limited force in the resource-rich northeast, but US sanctions—notably the Caesar Act—have stymied a Syrian economic revival, giving Washington a role in any future political settlement.
Success at risk
Back in 2015, Russia successfully shifted the balance of power in favour of al-Assad at his most crucial time. Diplomatically, Moscow successfully undermined the UN-backed Geneva peace process and—alongside Turkey and Iran—moved mediation for the Syria conflict to other tracks, notably the Astana and Sochi tracks. It deftly navigated regional powers’ conflicting interests and capitalised on divisions in the Syrian opposition, making Moscow a big player in any future political settlement. But this success is now at risk for several reasons.
The Syrian economy has sunk further, Damascus remains unable to control vast swathes of its territory, al-Assad is reluctant to implement reforms that would rehabilitate Syria's image, and the diplomatic process for an inclusive Syria has ground to a halt. Having succeeded in preventing the fall of the Syrian regime, Russia's diplomats demonstrated tactical ingenuity in negotiations, framing their efforts under the priority of combating terrorist groups, particularly Islamic State (IS).
Spoils of war
Russia locked in its wins with a 2017 legal agreement giving Moscow exclusive use of the Tartus naval base on Syria's Mediterranean coast free of charge for 49 years, with Russian sovereign jurisdiction over the base. Finally, Tartus is Russia's longed-for warm-water port, a goal since the time of the Tsars.
About 60km north of the Tartus base, Russia signed another agreement with Damascus to establish the Khmeimim Air Base near Latakia, also on Syria's Mediterranean coast. This treaty gives Russia free use of the base with no time limit. It is Russia's first sizeable foreign military base since the collapse of the Soviet Union. It is both practical and symbolic, solidifying Russia's military presence in Syria and advancing its geopolitical ambitions in the Middle East.
Official statistics report that 184 Russian military personnel have been killed in Syria from 2015-23, but this excludes Wagner losses. Up to 300 Russian mercenaries were killed in a single day during an attack on an oil field near Deir ez-Zor in 2018. Moscow will see these casualty numbers as small—more than 15,000 Soviet soldiers were killed in Afghanistan, and more than 70,000 have been killed in Ukraine, according to data analysis from the BBC last week.
In 2020, five years after Russia intervened in Syria, the then-defence minister, Sergei Shoigu, wrote in the Krasnaya Zvezda newspaper that it was necessary to preserve the Syrian state and to defeat IS. He added that Russian air support let the Syrian government retake 1,024 villages, bringing 88% of Syria under government control (although independent assessments suggest that Damascus controls much less than this).
Prior to Russia's intervention, 70% of Syrian territory was outside the control of Damascus, said Shoigu, but Russian aircraft conducted 44,000 combat sorties, killing 133,000 terrorists, including 4,500 Russian-speaking fighters.
