Connected Wars: How the U.S.–Israeli–Iranian Conflict Reshapes the Russia–Ukraine War
The complex nature of international conflicts in today’s world has led to a qualitative shift in understanding the course of wars and their dynamics. It is no longer possible to view wars and military tensions as isolated, self-contained events, but rather as part of an interconnected network of interactions, where developments in one conflict influence the shape and outcomes of others in different regions.
This analysis seeks to explore the implications of the U.S.–Israeli–Iranian war, which erupted on February 28, 2026, and for which a two-week ceasefire was announced at dawn on April 8, on the dynamics of the fighting in the Russia–Ukraine war. It also aims to examine the reverse effect—that is, how the war in Ukraine impacts the trajectory of the conflict in the Middle East.
Connected Wars:
The concept of “connected wars” has emerged to explain how contemporary conflicts are conducted across multiple fronts, yet within a broader structure characterized by a high degree of overlap and mutual influence. Each conflict is not only understood within its geographical boundaries but also in relation to parallel conflicts, where the interests of actors intersect and their roles become increasingly intertwined.
This phenomenon is marked by several key features. Chief among them is interdependence, where escalation or de-escalation in one conflict affects the dynamics of others. There is also the limitation of strategic resources, which forces actors to continuously redistribute capabilities across different fronts, creating reciprocal effects between conflicts. Additionally, there is the rapid transfer of military expertise and tactics between theaters of war, as warring parties seek to minimize material and human costs by leveraging accumulated experience. Moreover, the outcome of one conflict can influence how similar conflicts conclude in other regions.
Impacts of the Iran War:
Most assessments suggest that the war in the Middle East is influencing the operational theater in Ukraine, and that a prolonged conflict could benefit Russia, based on the following developments:
- Potential decline in Western military supplies to Ukraine:
A prolonged U.S.–Iran conflict may divert advanced military systems needed by Ukraine to counter Russian missiles toward the Middle East. This would force Kyiv to deplete its stockpile of interceptor missiles and reduce the effectiveness of its air defenses. Additionally, the Iran war could constrain Washington’s options in supplying Ukraine with offensive weapons.
In this context, Ukrainian President Volodymyr Zelensky, in an interview with the BBC on March 19, expressed concern that demand for U.S. interceptor missiles is exceeding supply. He added that Russian President Vladimir Putin seeks to exhaust Washington in the Iran war, limiting its ability to support Ukraine’s defenses. Consequently, Kyiv is accelerating efforts to strengthen its domestic defense industry, especially amid U.S.–European disagreements over both the Iran war and the settlement of the Ukraine conflict. Rising energy prices may also reduce European countries’ capacity to meet Ukraine’s military and economic needs, particularly in light of disagreements over a €90 billion support package.
- Increased intensity of mutual strikes between Moscow and Kyiv:
Since the escalation in the Middle East, military operations in Ukraine have seen a surge in reciprocal attacks. Russia has intensified its use of missiles and drones to deplete Ukrainian defenses, identify vulnerabilities, and disable critical infrastructure—especially energy networks and defense industry hubs. For instance, on the night of March 23–24, Moscow launched approximately 948 drones and 34 missiles, marking a record for the largest wave of air attacks in a single day since the conflict began, according to the Ukrainian Air Force. This aligns with Moscow’s efforts to prepare conditions for broader ground operations in the spring, reinforcing positions in Donbas and stabilizing southern defensive lines.
In response, Ukraine has expanded its deep-strike operations against Russian targets under an “offensive deterrence” strategy. On March 25, it launched 389 drones into Russian territory and intensified strikes on troop concentrations and supply lines in southern axes, aiming to disrupt Kremlin plans for ground advances.
Ukraine has also successfully targeted Russian military transport aircraft factories (March 18), potentially hindering maintenance and redeployment capabilities. Additional strikes on key facilities in Leningrad Oblast (March 23 and 25) caused partial disruptions to one of Russia’s largest Baltic oil export ports.
- Boost in Russian oil exports:
Russia’s economy has benefited from Middle East tensions, despite signs of strain due to the Ukraine war and Western sanctions on its energy sector. Disruptions to global shipping through the Strait of Hormuz—through which about 20% of global oil and LNG trade passes—along with reduced Gulf production due to Iranian attacks, have caused supply chain instability and sharp increases in global energy prices.
Moscow has capitalized on this by increasing oil exports to major Asian markets such as India and China. Notably, on March 12, the U.S. administration temporarily allowed the sale of Russian oil already at sea to mitigate market disruptions and curb price surges, ultimately boosting Russian state revenues.
- Partial diversion of U.S. attention from Ukraine:
The Middle East war has reduced momentum toward resolving the Ukraine conflict within U.S. priorities. Washington’s focus is now directed toward the war with Iran and restoring navigation through the Strait of Hormuz. Consequently, peace efforts in Ukraine have slowed, and trilateral talks between Washington, Moscow, and Kyiv—previously hosted in Abu Dhabi in January—have stalled. Instead, U.S. and Ukrainian negotiators met in Florida on March 22 without Russian participation.
Implications of the Ukraine War:
The prolonged Russia–Ukraine war has effectively become a testing ground for new combat strategies and weapon systems, shaping both military practices and the limits of Russian influence in the Middle East. This, in turn, affects regional conflict dynamics in several ways:
- Leveraging Ukrainian anti-drone technology:
As Iranian attacks on Gulf states intensify, President Zelensky has offered technical support to strengthen regional defense systems against drones. On March 5, he revealed that Ukraine had received a U.S. request to provide “specific technical support” in counter-drone defense in the Middle East, and Kyiv is preparing to deploy experts in interceptor drones to several countries. Zelensky’s late-March regional tour—including Saudi Arabia, Qatar, the UAE, and Jordan—focused on enhancing defense cooperation and knowledge exchange.
Ukraine has developed one of the most innovative and effective multi-layered air defense systems against drone swarms, successfully intercepting thousands of Russian attacks at relatively low cost—often just a few thousand dollars per interceptor drone.
- Caution against deep involvement in asymmetric warfare:
Asymmetric conflicts can drain the resources of stronger powers over time. Weaker actors may absorb initial shocks, adapt to sustained pressure, and expand the conflict beyond initial expectations. The Ukraine war serves as a cautionary model for voices within the U.S. administration, reinforcing a preference to avoid large-scale ground involvement in Iran. - Russia’s cautious stance on the Iran war:
The expanding scope and complexity of the Middle East conflict appear to have pushed Russia to avoid direct military involvement. Notably, the comprehensive strategic partnership agreement signed on January 17, 2025, between President Putin and Iranian President Masoud Pezeshkian does not include a mutual defense clause. Moreover, Russia’s ongoing engagement in Ukraine limits its ability to maintain influence in the Middle East, especially after the collapse of Bashar al-Assad’s regime in Syria in December 2024.
However, according to U.S. assessments, Russia may still be providing limited intelligence and military support to Iran—claims denied by Moscow. President Trump stated on March 13 that Russia might offer Iran “some help,” while some U.S. media outlets have reported similar findings.
Interconnected Balances:
The Russia–Ukraine war and the U.S.–Israeli–Iranian war illustrate the deep interconnection of modern conflicts, where developments in one theater generate ripple effects in another. Both wars contribute to reshaping regional and global power balances.
On one hand, tensions in the Middle East may benefit Moscow by stretching U.S. military resources, potentially reducing support for Kyiv. Russia also gains from increased oil revenues, which help finance its war effort.
On the other hand, Ukraine fears that a prolonged Middle East conflict could undermine U.S. support, particularly in providing interceptor missiles, while rising war costs may strain European backing.
At the same time, Middle Eastern countries may benefit from Ukrainian expertise in drone warfare to counter Iranian threats—enhancing defense efficiency, reducing costs, and strengthening regional security. Meanwhile, Kyiv views its cooperation with U.S. partners in the Middle East as leverage to secure better negotiating terms in its confrontation with Russia.
