In March 2026, as the dust settled over Tehran in the aftermath of a joint U.S.-Israeli operation targeting Iran’s leadership, the world watched Russia’s muted reaction with interest. Despite having signed a strategic partnership treaty with Tehran barely a year earlier, Moscow’s response was limited to diplomatic censure and appeals for peaceful resolution.

Kremlin spokesman Dmitry Peskov addressed the situation, confirming that Iran had not sought military assistance from Russia. “There were no requests from Iran in this case,” Peskov stated on March 5th, during a press briefing.

To analysts well-versed in the Moscow-Tehran dynamic, the restrained response was expected. “The relationship has always been transactional,” explained Ksenia Svetlova, executive director at the Regional Organization for Peace, Economy and Security (ROPES) and an associate fellow at Chatham House. “Russia acts according to its own interests.”

Though recent years have seen Iran and Russia draw closer—particularly following Russia’s 2022 invasion of Ukraine—experts maintain that this partnership falls short of a full-fledged alliance. Instead, it is a pragmatic arrangement, evolving through a complex web of convenience, competition, and shifting global strategies.

The Shadow of Turkmenchay

The relationship between Russia and Iran dates back nearly 200 years, beginning with the Treaty of Turkmenchay in 1828. This treaty, following Persia’s military defeat, forced it to surrender significant territory in the Caucasus to the Russian Empire. It remains a deeply resonant symbol of foreign domination in Iran’s political consciousness.

In the twentieth century, Russia’s relationship with Iran shifted dramatically. Before the 1979 Islamic Revolution, Moscow maintained relatively stable ties with Iran under Shah Mohammad Reza Pahlavi. “It actually had good relations with the Shah who visited Moscow after World War II,” Svetlova said.

“But Communist Russia was very suspicious of Islamist Iran after the 1979 revolution,” said Svetlova. It was a mutual distrust; Ayatollah Ruhollah Khomeini denounced both Cold War superpowers, calling the United States the “Great Satan” and the Soviet Union the “Lesser Satan.” 

Even during the Iran-Iraq War of the 1980s, the Soviet Union maintained ties with Tehran while simultaneously supplying weapons to Iraq. “The Soviet Union was very suspicious of Islamist Iran,” Svetlova said. “Even after the revolution, the relationship could not really be considered an alliance.”

The Drone Marriage

In recent years, however, geopolitical pressures pushed the two countries closer together. Russia’s full-scale invasion of Ukraine in 2022 created new military cooperation between Moscow and Tehran. 

Though Russia and Iran have not shared a land border since the 1991 collapse of the Soviet Union, they remain “neighbors” via the Caspian Sea. This “blue border” became a vital artery in 2022 when Iran supplied the Shahed-series drones used in Ukraine, that Russia has used extensively in attacks on Ukrainian infrastructure.

Vice Adm. Robert S. Harward, a retired Navy SEAL and former deputy commander of U.S. Central Command, said the partnership has had direct consequences on the battlefield. “Sadly, the world is just now getting a taste of Iranian drones. But there’s one group that already knows them well, the Christians in Ukraine,” Harward said. “Close to 600 Ukrainian churches have been destroyed by Russian attacks, including from the Iranian Shahed drones.”

Carrie Filipetti, executive director of the Vandenberg Coalition and a former deputy assistant secretary of state, argued that Russia’s continued use of Iranian drones against Ukrainian targets underscores the depth of the military relationship, while its calls for restraint in the current conflict highlight a fundamental contradiction. “If Russia were serious about peace, we would see a ceasefire with Ukraine months ago,” she said. “Yet, Putin continues to attack Ukrainian cities, churches and civilians with Iranian drones day after day.”

And yet, Russia’s dependence on Iranian drones during the early stages of the Ukraine war has also diminished as Moscow built its own production capacity. A report cited by the Washington Post found that Russia has “transitioned from importing Iranian Shahed drones to mass-manufacturing them” under the name Geran-2.

Limits and Intelligence

War Secretary Pete Hegseth said Tuesday that Russia “should not be involved” in the escalating conflict between the United States, Israel and Iran, as reports that Russia has provided information that could help Iran identify U.S. military assets in the Middle East emerged. Moscow has not publicly confirmed the claims. 

“I believe Russia is providing Iran intelligence to more effectively target Americans, our allies and partners in the CENTCOM region,” said Lt. Gen. Richard Y. Newton III, a retired Air Force officer who served as assistant vice chief of staff of the U.S. Air Force. “It’s absolutely clear Russia is not our friend.”

“They are doing for the Iranians without spending money, spending troops or spending equipment,” Svetlova added. “They share knowledge. They supplied the Iranians with a target list, basically, through their satellites – American targets, but also air targets in the Gulf and Iraq.”

Harward argued that confronting this growing cooperation requires a broader strategy. “If we want to break the threat of the increasingly dangerous Russian-Iranian alliance, we need to fully decimate Iran’s capabilities to threaten our allies and the United States – and we need to continue to support Ukraine and get Europeans to do their part,” he said.

Filipetti remains skeptical of Moscow’s role as a mediator. “The idea that Russia would call on the U.S. and Israel to cease military operations against the regime in Iran and suggest that we should negotiate is absurd,” Filipetti said.

Although Russia is falling short of helping Iran in a straightforward military way, experts say the cooperation in the world of intelligence has been profound. 

Ultimately, Newton argued that Russia’s actions should be viewed through the lens of President Vladimir Putin’s broader geopolitical goals. “Putin only does what serves Putin, and right now escalating the war in the Middle East and driving up oil prices only serves his interests so he can continue to fund his war machine against Ukraine,” he said.
