Iran War's $200 Billion Cost Reshapes US Stability
Iran War's $200 Billion Cost
In May 2026, inflation hit a three-year high of 4.2%, and gasoline prices reached $4.48 per gallon, surging over 40% from the previous year, American Progress reported. This surge, alongside the closure of the Strait of Hormuz, which handles 20% of global oil and natural gas, triggered a severe energy and food price shock. These events contributed to the Iran war's $200 billion cost and signaled a structural erosion of US fiscal flexibility. Wikipedia and the American Enterprise Institute both documented the profound energy and food price shock. Concurrently, 10-year Treasury bond yields rose by approximately 30 basis points to 4.25%, increasing borrowing costs for the government, businesses, and households, as the American Enterprise Institute and American Progress found. The Congressional Budget Office (CBO) projected that even before this war, deficits were set to exceed 6% of GDP, and public debt would surpass World War II levels by 2030, a forecast the American Enterprise Institute echoed.
Spain, France, Germany Block US Operations
Major European powers acted unilaterally or in opposition to US operations, with Spain closing its airspace, France blocking US and Israeli aircraft, Germany declaring neutrality, and the UK initially refusing base access, Small Wars Journal detailed. The publication also asserted that the conflict caused the "deepest damage" to the transatlantic alliance. The US postponed Foreign Military Sales (FMS) deliveries to Baltic and Scandinavian NATO members, further eroding trust, a situation Small Wars Journal observed "does not mend quickly."
Iran's Strait of Hormuz Toll Regime
Iran now exercises an unprecedented degree of control over the Strait of Hormuz, imposing a de facto toll regime that has forced countries like India and Pakistan to negotiate passage directly with Tehran, Small Wars Journal documented. The publication also highlighted how the war exposed the fragility of Washington's security umbrella for Gulf partners. The Middle East Council found that Gulf states have accelerated investments in cyber deterrence and indigenous AI capabilities. Saudi Arabia expanded defense cooperation with Pakistan and Turkey, formalized by a mutual defense pact in September 2025, the European Union Institute for Security Studies reported. Gulf states are actively diversifying beyond the US; Saudi Arabia and the UAE acceded to BRICS, and Bahrain applied in October 2024, The Century Foundation, Atlantic Council, and Vision of Humanity jointly observed. These nations are deepening defense ties with France, the UK, South Korea, Turkey, Russia, and China to reduce reliance on the American military system, a shift the Middle East Council emphasized.
Russia and China Coordinate Iran Support
Russia and China actively coordinated to support Iran, providing intelligence, military supplies, and economic aid, Small Wars Journal and the Georgetown Journal of International Affairs jointly reported. This deepening alignment, driven by shared interests in exploiting US "strategic insolvency," represents a durable structural shift toward a multipolar security order, both publications concluded. American Progress, Small Wars Journal, the Georgetown Journal of International Affairs, and the Atlantic Council detailed how Russia benefited from elevated oil prices and Western distraction from Ukraine, while China secured preferential passage through the Strait of Hormuz and acted as Iran's largest oil buyer. The Georgetown Journal of International Affairs and the Atlantic Council highlighted the potential for a two-front challenge for Washington if China escalates in the Taiwan Strait and South China Sea. Small Wars Journal and the Georgetown Journal of International Affairs explained that the diversion of advanced interceptors, strategic bombers, and carrier assets to the Middle East left Ukraine under-supplied and the Indo-Pacific under-resourced. The rapid depletion of munitions, such as the potential exhaustion of the entire US interceptor inventory in four to five weeks, demonstrated severe manufacturing bottlenecks, Small Wars Journal observed.
Multi-Billion Dollar Interceptor Costs
The financial costs of expending multi-billion dollar interceptor stockpiles, coupled with fiscal strain and industrial limitations, will likely raise the strategic threshold for initiating military interventions abroad compared to historical lower-cost conflicts. This structural erosion of US fiscal flexibility and fractured alliance network will, in turn, constrain US foreign policy options, significantly raising the bar for future military interventions.
