Iran’s growing support for Russia during the Ukraine war highlights a shifting global security landscape shaped by deepening cooperation among authoritarian states. In testimony before the Commission on Security and Cooperation in Europe, experts outlined how ties between Moscow and Tehran have evolved and what this means for the United States and its allies.
The relationship between Russia and Iran must be understood within a broader context of emerging strategic threats. Analysts argue that countries such as Russia, China, North Korea, and Iran are increasingly coordinating to counter U.S. influence and challenge democratic systems. This alignment is not accidental but driven by deliberate political decisions to strengthen their global position. Rather than being a reaction to U.S. actions, these partnerships reflect shared interests in reshaping the international order.
Historically, Russia-Iran relations have transitioned from rivalry to cooperation. While mistrust defined earlier centuries, recent decades have seen a more transactional and now increasingly strategic partnership. After the collapse of the Soviet Union, both countries chose to collaborate in areas such as defense and nuclear development. Their cooperation deepened further during the Syrian conflict and has expanded significantly since the start of the Ukraine war.
Since 2022, Iran has played a direct role in supporting Russia’s military efforts. It has supplied thousands of drones, including Shahed-series unmanned systems, which have been widely used in attacks on Ukrainian infrastructure. Iran has also assisted Russia in developing domestic drone production capabilities and reportedly provided ballistic missiles, ammunition, and military training. Beyond military aid, Tehran has helped Moscow evade sanctions, particularly through the use of “ghost fleets” to continue oil exports.
In return, Russia has offered Iran a range of military, technological, and economic support. While some high-profile weapons transfers remain unconfirmed, cooperation has included aircraft deliveries, satellite launches, and assistance in Iran’s space and missile programs. Russia has also played a role in advancing Iran’s nuclear energy sector and has reportedly provided surveillance and cyber capabilities to strengthen the regime’s internal control mechanisms.
This partnership extends beyond bilateral cooperation and reflects broader geopolitical ambitions. Iran’s inclusion in organizations such as the Shanghai Cooperation Organization and BRICS, along with joint military exercises involving China, signals its deeper integration into a network of states seeking alternatives to Western-led systems. At the same time, the relationship has limits, shaped by strategic calculations and competing interests.
The Ukraine war has demonstrated how Iran’s relatively low-cost military technologies, particularly drones, can have a significant impact on modern warfare. These systems have allowed Russia to sustain long-range attacks while conserving more advanced weapons. The conflict has also revealed how cooperation between allied states can amplify their capabilities in both conventional and unconventional domains.
Policy experts suggest that addressing this partnership requires a multifaceted approach. This includes increasing pressure on both Russia and Iran through sanctions, strengthening support for Ukraine, and investing in counter-drone technologies. There is also a focus on supporting democratic movements within Iran and expanding internet access to counter state control. Additionally, enhancing international coordination and reinforcing defense industrial capacity are seen as critical steps in responding to these evolving threats.
Overall, the deepening Russia-Iran partnership underscores the complexity of modern geopolitical alliances. The lessons from Ukraine highlight not only the changing nature of warfare but also the importance of strategic coordination among states in shaping global security outcomes.
