stopped short of describing the exercise as a form of deterrence against hostile action towards Iran, the message was clear: both military powers were showing solidarity with Tehran amid escalating political-military tensions.

A few examples illustrate the point. Shortly after the US-Iran crisis erupted, Moscow was on the move, backing Iran politically and militarily. On 7 January, Russian President Vladimir Putin made a surprise visit to Syria before visiting neighbouring Turkey. The aim was not just to show continuing support for the regime of Syria’s President Bashar al-Assad. The fact that Putin met with Assad at Russia’s regional operations and command centre was both symbolic and telling: Moscow keeps a close eye on regional developments and is ready to react to any form of escalation.

Following the visit to Turkey, Putin attended large-scale naval exercises held by the Russian Navy in the Black Sea. The timing and locale of the exercises was equally revealing – Russia was again showcasing its military might, including offensive firepower, as a warning to the US and its allies that it will not act as a passive observer should Iran come under attack.

Russia’s determination to contain US actions in the region was also highlighted by a near collision between Russian and US warships in the Arabian Sea on 9 January, the same day as the Russian naval exercises in the Black Sea. Russian intelligence-gathering vessel RFS Ivan Hurs nearly hit the USS Farragut destroyer while shadowing operations of a US aircraft carrier battle group in the area.

Russian air defence units have been closely monitoring airspace over and around Iran and probably sharing intelligence with Tehran. On 17 January, Russian Foreign Minister Sergei Lavrov stated that at least six fifth-generation F-35 tactical aircraft were spotted near Iranian airspace shortly after Iranian missile attacks on US facilities in Iraq.

Russia’s stance on foreign intervention in Iran is likely driven by several considerations:

  • An invasion of Iran would likely become a protracted and bloody campaign for any invading force, even after the Iranian regime’s military defeat;
  • Experience in Libya and Iraq suggests that a peaceful and bloodless transition of power would be highly unlikely, creating a regional arc of instability extending from Afghanistan right through to the Israeli border;
  • The balance of power in the Persian Gulf and the larger Middle East would shift dramatically, triggering further geopolitical instability and conflict.

In addition, other factors may influence Moscow’s behaviour:

  • Any military operations against Iran could involve coordinated strikes from the Caspian Sea (Azerbaijan’s airfields, should Baku grant access to the US Air Force), which Russia considers a zone of immediate strategic significance;
  • Any significant environmental impact and resulting humanitarian crisis from strikes on Iran would affect Russia’s southern regions;
  • US military presence in northern Iran with direct access to the Caspian would be viewed in Moscow as a direct threat to its national security.

Still, it would be premature to assume that Russia has unconditionally taken the side of Iran. On one hand, Moscow used an array of diplomatic and military signals to demonstrate that Iran is not alone, and that unilateral action will not go unanswered. On the other, it applied pressure on Tehran to restrain its actions and avoid further escalation.

Despite the two countries’ improved bilateral relations, strengthening strategic dialogue, and increasing economic and military cooperation, Iran is a partner of convenience for Moscow – not a close friend or a client – and there is little doubt that Russia has benefited from the killing of Solemaini, who was instrumental to Iran’s strategic leverage in Syria, a concern for Moscow for some time. His death will have serious long-lasting impact on Iran’s capacity to influence the Asad regime and on the freedom that Iranian-backed units exercised in Syria. Putin’s surprise visit to Damascus indicates that Moscow was quick to fill the power vacuum and show Asad the dominant factor now in Syria.

Moreover, the Russian budget profited from the hike in oil prices.

Moscow’s involvement highlights both the complexity and the potential fragility of the Iran crisis, especially when two nuclear powers provoke each other against a backdrop of regional tensions. In Syria, there have been a number of reports of Russian and US forces blocking each other’s operations. In the absence of an immediate political solution and a desire to defuse tensions, the crisis in the Gulf will continue to be a ticking time bomb.
