Iran War: Why Is Russia Not Coming to Tehran’s Aid?

Russian Diplomacy Faces Scrutiny Amid Escalation

The Iranian government, which has few international allies, has relied heavily on Russian backing during recent US-Israeli attacks. Yet, Moscow’s response has fallen short of expectations. Just hours after Israeli and American airstrikes targeted Tehran on Saturday, Russia’s UN ambassador, Vassily Nebenzia, condemned the actions as “an unprovoked act of armed aggression against a sovereign and independent UN member state.”

Economic Ties and Strategic Projects

Despite this diplomatic remark, Russia remains a key ally of Iran. However, its absence in military intervention raises questions. Nikita Smagin, a Middle East analyst based in Azerbaijan, noted that the two nations collaborate on critical economic ventures, such as the North-South transport corridor. “This 7,200-kilometer multi-mode network is vital for Russia, especially after its transit routes were disrupted by the Ukraine invasion in 2022,” he explained.

Smagin highlighted that the project, signed in 2000 by Russia, India, and Iran, is nearly complete, with 75% of its infrastructure already operational. The corridor passes through Azerbaijan, offering a potential alternative to Western sanctions. Yet, Russia’s support has not translated into direct military action, leaving Iran in a precarious position.

Military and Intelligence Collaboration

Russia has provided Iran with military assets, including Shahed drones since 2023, which have significantly influenced the Ukraine conflict. Julian Waller, a research analyst at the Center for Naval Analyses, emphasized that Iran’s drones reshaped the war’s dynamics, even as Russia now produces its own versions. “The partnership isn’t ideological—Russian leaders don’t necessarily admire Iran,” Smagin added, noting that both countries face Western sanctions, unlike Turkey or Egypt, which might abandon trade with Moscow under pressure.

Gregoire Roos of Chatham House suggested that Iran has become a mentor for Russia, sharing strategies to navigate sanctions. “Iran’s experience in circumventing economic restrictions has guided Moscow’s approach,” Roos said. However, experts agree that Russia is unlikely to intervene actively in the current conflict.

Expectations and Disappointment

Experts like Mojtaba Hashemi argue that Iran misjudged Russia’s commitment. “Tehran anticipated expanded military cooperation, intelligence sharing, and a strong deterrent message,” he said. Hashemi pointed out that Russia and China have prioritized other challenges, offering Iran weapons but not direct support.

Meanwhile, Mohammad Ghaedi, a professor at George Washington University, noted that Iranian leaders had long questioned Moscow’s reliability. “Ahmadinejad once claimed, ‘Russia has always betrayed the Iranian nation,’ and President Pezeshkian observed that ‘countries we trusted did not assist us during the war,’” Ghaedi recounted.

Opportunities for Moscow

Chatham House’s Roos speculated that a protracted Iran conflict could benefit Russia. “The focus on Iran might reduce attention on Zelenskyy, while Washington struggles to sustain its efforts,” he said. This strategic calculation underscores the complex dynamics at play, where Russia balances its alliances and interests in a rapidly shifting geopolitical landscape.
