WASHINGTON -- Russia's partnership with Iran has become one of the most influential strategic partnerships in today's geopolitical landscape.While Moscow and Tehran have stopped short of a formal military alliance, their cooperation in drones, intelligence, sanctions evasion and internal security has deepened since Russia's full-scale invasion of Ukraine.In an interview with RFE/RL, Nicole Grajewski, an expert on Russian-Iranian relations at Sciences Po and the Carnegie Endowment for International Peace, explains how the conflicts in Ukraine and the Persian Gulf have become increasingly intertwined -- and how far Russia is willing to go to support Iran.RFE/RL: As regional strikes and maritime escalation intensify across the Persian Gulf, how is the deepening partnership between Moscow and Tehran reshaping both the war in Ukraine and the broader security crisis in the Middle East?Nicole Grajewski: What's fairly apparent with the current war and the war in Ukraine is how intertwined the Russia-Iran relationship is and how it's transformed.For example, Iran provided Russia with the Shahed drones that were used quite extensively in Ukraine. In return, Russia has been providing crucial support to Iran when it comes to satellite imagery, potentially targeting support, as well as training, operational assistance, and data sharing.So there's a kind of synergy that actually derived from the war in Ukraine, and you see it translating into this current war. Additionally, many of the same threats that Ukrainians face on a daily basis are what US Gulf allies are currently facing. During the war, Ukraine reached out to Gulf partners when it came to counter-UAV and counter-drone warfare.There are a lot of connections between these two wars, and I think it's a mistake not to analyze them together because they're inextricably tied through the two actors involved, but also through the same technologies and the sharing of resources.
