As the geopolitical landscape in the Middle East faces yet another seismic shift, the ongoing US-Israel war on Iran has brought a critical question to the forefront: who will pay for this massive military operation? According to recent statements from the White House in late March 2026, United States President Donald Trump is heavily considering a familiar strategy—asking Arab nations to shoulder the financial burden of the conflict.
This proposed funding mechanism echoes a long-standing pattern in US foreign policy: leveraging global and regional allies to finance military interventions. But with the current dynamics in the Middle East, will this historical playbook work again?
The Financial Blueprint for the Iran Conflict
White House spokesperson Karoline Leavitt recently confirmed that President Trump is highly interested in urging Arab countries to cover the tens of billions of dollars required for the ongoing military campaign against Iran. While official requests have not yet been formalized, the administration is floating the idea of shifting the financial weight to regional players.
For the US, this strategy is not just about saving domestic taxpayer dollars; it is about forcing nations that theoretically benefit from neutralized regional threats to pay a premium for American military involvement. However, this approach has triggered significant debate among international analysts and Middle Eastern governments.
Economic Shockwaves: The Strait of Hormuz and Oil Prices
The financial implications of the war extend far beyond direct military costs. Shortly after the conflict erupted in late February 2026, Iran closed the Strait of Hormuz, a vital maritime chokepoint. In peacetime, approximately 20% of the world's liquefied natural gas and oil supplies pass through this narrow waterway.
The closure has sent shockwaves through the global economy, driving the global benchmark for Brent crude oil to a staggering $116 per barrel—nearly double its pre-war price. While the United States remains largely self-sufficient regarding energy resources, its international partners are heavily reliant on these Middle Eastern exports. The Trump administration has hinted that countries dependent on these shipping lanes should take on the burden of resolving the crisis, even if it means halting the war without reopening the strait.
Meanwhile, Tehran has drawn its own financial line in the sand, demanding that the US pay reparations to Iranian victims as a strict precondition for any ceasefire agreement.
Why Experts Argue Israel Should Bear the Cost
Unlike previous conflicts in the region, Middle Eastern governments—particularly members of the Gulf Cooperation Council (GCC)—did not request American military intervention. In fact, prior to the strikes in late February, GCC nations actively advocated for diplomacy and de-escalation to prevent a full-scale war.
Geopolitical experts, including Zeidon Alkinani from the Arab Perspectives Institute, note that asking Arab states to fund this specific conflict lacks logical grounding. Since the GCC pushed against the military escalation, many analysts argue that the financial responsibility should fall on the nation that actively campaigned for the offensive. In this context, experts suggest that Israel, being the primary driving force behind the push for US military action against Iran, should be the one to handle the associated costs.
A Look Back: The US History of Outsourcing War Costs
If Washington successfully pressures Arab nations to finance the war on Iran, it will merely be the latest chapter in a long history of making other countries pay for conflicts.
The 1990-1991 Gulf War
The most direct parallel to the current proposal is the Gulf War. After Iraq invaded Kuwait in 1990, the US led a massive global coalition to expel Iraqi forces (Operation Desert Storm). The war cost approximately $61 billion at the time (around $140 billion today). However, the US only paid about 12% of the bill. The remaining 88% was funded by allied nations, with Saudi Arabia and Kuwait covering more than half of the total expenses, alongside significant contributions from Japan, Germany, and the UAE.
Post-World War II Financial Strategies
Following World War II, the US utilized different financial mechanisms. While the US funded the Marshall Plan to rebuild Europe, defeated nations like Germany and Japan were forced to pay massive reparations and accept military occupation. Today, both Germany and Japan still spend billions of dollars annually to maintain US military bases on their own soil.
The Ukraine Conflict Shift
A more recent example of this financial burden-shifting is the ongoing war in Ukraine. While the US was initially the largest financial and military backer of Kyiv following Russia's 2022 invasion, the landscape shifted dramatically upon Trump's return to the presidency in January 2025. The administration slashed US financial support by 99%, forcing European allies to fill the massive funding gap. Instead of providing direct aid, Washington pivoted to selling billions of dollars in military equipment—such as Patriot air defense systems—to Europe, effectively turning the conflict into a lucrative venture for the US defense industry.
Conclusion: A Risky Financial Strategy
As the US-Israel war on Iran continues to unfold, the question of funding remains a major point of contention. While the United States has a successful track record of compelling allies to pay for its military campaigns, the unique geopolitical dynamics of 2026 present new challenges. With Arab nations facing the direct fallout of a war they tried to prevent, Washington's attempt to pass the bill may test the limits of its diplomatic leverage in the Middle East.
