Russia-Iran Alliance: How Ukraine War and Iran War Connect
Russia-Iran Alliance: How Ukraine War and Iran War Connect
On the surface, the war in Ukraine and Operation Epic Fury in Iran appear to be separate conflicts — different regions, different aggressors, different stated objectives. But beneath the surface, these two wars are deeply intertwined through a military alliance that has reshaped the global order.
Russia and Iran have been building a strategic partnership for years. The Ukraine war accelerated it. The Iran war has cemented it. Understanding how these two conflicts connect is essential for grasping the geopolitical landscape India must navigate.
The Arms Pipeline: A Two-Way Street
The most tangible connection between Russia and Iran is the arms trade — and it flows in both directions.
Iran to Russia: Beginning in 2022, Iran supplied Russia with thousands of Shahed-136 kamikaze drones for use in Ukraine. These cheap, effective weapons terrorized Ukrainian cities and infrastructure, forcing Kyiv to divert expensive air defence systems to counter $20,000 drones. Iran also reportedly provided ballistic missile components and training.
This supply relationship was transformative for Russia. Facing Western sanctions that cut off semiconductor and precision component supplies, Russia found in Iran a willing technology partner. Iranian drone technology — developed and battle-tested against Saudi Arabia, Israel, and various proxy targets — gave Russia an asymmetric capability it desperately needed.
Russia to Iran: In return, Russia provided Iran with advanced air defence systems, including components of the S-400 system, Su-35 fighter aircraft (agreed in principle, with deliveries reportedly underway before the crisis), and critically, intelligence and electronic warfare technology.
The irony is painful: some of the air defence systems that Operation Epic Fury had to suppress on February 28 were Russian-supplied. American and Israeli pilots faced radar systems and missile batteries that incorporated Russian technology — technology that Russia, in turn, had developed partly using experience gained fighting Western-supplied weapons in Ukraine.
The Energy Connection
Russia and Iran are both petroleum superstates, and their energy relationship has deepened dramatically since both came under Western pressure.
Pre-crisis cooperation: Russia and Iran coordinated within OPEC+ to manage global oil supply and prices. This coordination wasn't always smooth — they had different price preferences — but it gave both countries leverage over global energy markets.
Sanctions evasion: Both countries developed sophisticated sanctions-evasion networks. Russian and Iranian oil was shipped using "dark fleets" of aging tankers with obscured ownership, transferred through ship-to-ship operations in open water, and sold to willing buyers (primarily China and India) at discounted prices.
India was a significant customer for both Russian and Iranian discounted oil. In FY2024-25, Russian oil constituted nearly 35% of India's imports, purchased at discounts that saved Indian refiners billions. Iranian oil, though smaller in volume, was also procured through various channels.
Post-crisis dynamics: With Iran's oil infrastructure partially destroyed and the Strait of Hormuz closed, the immediate energy dynamic has shifted. Russia is now the primary alternative supplier for countries (including India) that previously relied on Gulf oil. Russian oil — already discounted due to Western sanctions — has become even more strategically important.
This gives Russia enormous leverage. Moscow can prioritize supply to favored customers, adjust pricing to reward or punish diplomatic positions, and use energy as a tool of influence more effectively than before the crisis.
The Ukraine War Connection: Strategic Distraction
From Moscow's perspective, the Iran war has been a strategic gift — however much they publicly lament it.
US military distraction: The deployment of American military assets to the Persian Gulf for Operation Epic Fury has reduced the resources available for supporting Ukraine. Precision munitions, intelligence assets, naval forces, and command attention are finite — and the Iran operation is consuming significant capacity.
European energy pressure: Europe, which had partially weaned itself off Russian gas after 2022, now faces renewed energy pressure as the Iran war disrupts global oil and gas markets. European natural gas prices have surged alongside oil, increasing the economic pain of the Ukraine conflict for EU nations that must simultaneously support Ukraine and manage their own energy costs.
Diplomatic bandwidth: International diplomatic attention has shifted from Ukraine to Iran. The UN Security Council, which was consumed by Ukraine resolutions for three years, is now focused on the Iran crisis. This reduces the diplomatic pressure on Russia and gives Moscow more room to maneuver in Ukraine.
Military lessons: Russia is carefully studying Operation Epic Fury for military lessons applicable to its own operations. The US-Israel air campaign against Iranian air defences, the precision strike methodology, and the drone and electronic warfare tactics all provide valuable intelligence for Russian military planners.
The Alliance Framework
Russia and Iran's relationship has evolved from a transactional arms-for-oil arrangement into something approaching a genuine strategic alliance. The key elements include:
Shared adversary: Both nations identify the United States as their primary strategic threat. This shared adversary creates a powerful bonding force — whatever their differences on other issues, opposing American hegemony is a unifying objective.
Complementary capabilities: Russia has advanced military technology (air defence, fighter aircraft, electronic warfare) that Iran wants. Iran has drone technology, regional proxy networks, and geographic position that Russia values. The exchange is mutually beneficial.
Economic interdependence: Sanctions on both countries have pushed them toward bilateral trade in national currencies (rubles and rials), barter arrangements, and alternative financial infrastructure that bypasses Western systems. This economic interdependence is self-reinforcing — the more they trade with each other, the less vulnerable they are to Western economic pressure.
Ideological alignment: While Russia's Orthodox nationalism and Iran's Islamic theocracy seem incompatible, both share a "civilizational state" self-concept that rejects Western liberalism as a universal model. This ideological affinity, while not deep, provides a narrative framework for cooperation.
The Nuclear Dimension
One of the stated objectives of Operation Epic Fury was the destruction of Iran's nuclear program. But the Russia-Iran alliance complicates the nuclear picture significantly.
Russia has been Iran's primary civilian nuclear partner for decades, building the Bushehr nuclear power plant. Russian nuclear scientists and engineers have maintained a presence in Iran's nuclear establishment.
The question the world must now ask: even if Operation Epic Fury destroys existing nuclear facilities, can the knowledge be eliminated? Iranian nuclear scientists who worked alongside Russian counterparts have expertise that can be reconstituted. And Russia, which has its own reasons to maintain an Iranian nuclear hedge against Western power, has no incentive to help permanently denuclearize Iran.
For India — a nuclear-armed state that has long been concerned about nuclear proliferation in its neighborhood — this dimension is particularly significant. A reconstituted Iranian nuclear program, potentially more secretive and more deeply embedded in the Russia-Iran alliance, could emerge from the ruins of the facilities that Operation Epic Fury destroyed.
India's Delicate Position
India's relationship with both Russia and Iran has historically been warm. India-Russia ties, forged during the Cold War, have survived multiple geopolitical shifts. India-Iran ties are rooted in cultural connections, energy trade, and the strategic Chabahar port project.
The Iran war has complicated both relationships:
India-Russia: India's decision to side with Israel-US in the Iran conflict puts it on the opposite side of Russia's stated position. While Russia and India have managed to maintain their relationship despite India's Ukraine stance (which was neutral rather than pro-US), the Iran alignment is more difficult for Moscow to overlook.
However, Russia needs India as an oil customer and as a diplomatic interlocutor. The economic incentives for maintaining the relationship remain strong on both sides. India imported significant volumes of Russian oil in 2024-25, and with Gulf oil disrupted, that volume is likely to increase.
India-Iran: India's alignment with the forces that attacked Iran and killed Khamenei is a fundamental rupture in the India-Iran relationship as it existed. Whatever government eventually takes power in Tehran will remember India's position.
The Chabahar port — India's strategic investment that provides access to Afghanistan and Central Asia while bypassing Pakistan — is at risk. A post-war Iranian government aligned with Russia and China might renegotiate or cancel the Chabahar agreement, depriving India of a critical strategic asset.
The New World Order Taking Shape
The Russia-Iran alliance, expanded to include China (see our earlier analysis), is one pillar of what analysts call the emerging "multipolar" or "polycentric" world order. On the other side stands the US-Israel-EU-Japan-Australia grouping.
India's traditional position has been strategic autonomy — maintaining relationships with all sides while aligning formally with none. The Iran war is testing this posture to its limits.
The Russia-Iran-China axis offers India cheap energy, counterbalance to Pakistan, and diplomatic flexibility. The US-Israel grouping offers technology access, security cooperation, and market access. Choosing one over the other permanently would be costly; maintaining both becomes harder with each crisis.
What Comes Next
The Russia-Iran alliance will outlast the current crisis. Regardless of how the Iran war ends, the structural forces pushing Moscow and Tehran together — shared adversary, complementary capabilities, economic sanctions — will persist.
For India, this means:
Energy diplomacy becomes paramount: India must maintain its ability to buy oil from Russia (and eventually Iran) regardless of Western preferences. Energy security for 330 million households cannot be subordinated to alliance politics.
Defence diversification continues: India's ongoing shift from Russian to Western military hardware is partially driven by reliability concerns (spare parts, upgrades). The Iran war reinforces this trend — India cannot depend on a single supplier aligned with its potential adversaries.
Strategic autonomy must be preserved: Despite the pressure to choose sides, India's long-term interests are best served by maintaining relationships across the geopolitical divide. This requires sophisticated diplomacy and a willingness to accept criticism from all sides.
The Russia-Iran alliance is a reality that India must accommodate, not a problem it can solve. The challenge is managing the relationship such that India's security, energy, and economic interests are protected while the great power competition that defines this era plays out around it.
