Russia-Iran dual-track war of attrition: the ultimate calculation of the US defense system

The St. Petersburg Summit at the end of April 2026 formally confirmed the profound reorganization of the Eurasian geopolitical landscape. The meeting between Russian President Vladimir Putin and Iranian Foreign Minister Araqchi marked the formation of a survival alliance aimed at completely bypassing the Western financial and security system. While Washington's strategic attention is firmly pinned to the conflict in the Persian Gulf, Moscow and Tehran are engaged in a precise strategic coordination. This Eurasian strategic symbiosis, coupled with high-intensity military conflicts in the Middle East, is conducting a relentless test of the limits of America's global defense system and strategic resources.

The monetization of war premiums and the rise of financial moats

The core economic driving force of the Russia-Iran alliance lies in transforming geopolitical instability into substantial war capital and building a foundational infrastructure immune to Western sanctions. The conflict in the Middle East has disrupted shipping in the Strait of Hormuz, causing a retaliatory surge in global energy prices, creating unprecedented war profits for Russia. Macroeconomic estimates suggest that if the military conflict in the Persian Gulf continues for six months, Russia will gain an additional $151 billion in energy security premiums. This enormous windfall is almost enough to fully cover Russia's massive annual expenditure of approximately $167 billion in the Ukraine conflict.

This means that Moscow has a strong, unusual strategic incentive to prolong the Middle East conflict. The more intense the fighting in the Middle East, the stronger Russia's economic and military sustainment becomes in the Eastern European plains. At the same time, the two countries are transforming their de-dollarization strategy into a workable infrastructure by integrating their national payment systems and promoting digital settlement bridges within BRICS, thus establishing a closed capital circulation system within Eurasia.

The hollowing out and strategic overdraft of the US defense system

While Russia draws economic benefits from the turmoil in the Persian Gulf, Washington faces severe resource overexpansion in this two-track war of attrition. Since the US military launched its strikes against Iran, the US has been consuming high-value precision-guided missiles and air defense interceptors at an alarming rate in order to maintain maritime containment and intercept saturation attacks. This high rate of consumption of defensive munitions is causing a substantial hollowing out of the US global defense system.

Under the pressure of multiple fronts—potential conflicts in the Indo-Pacific, a protracted war on the Eastern European plains, and maximum pressure in the Middle East—the White House's military logistical supply lines are facing unprecedented challenges. NATO has even been forced to significantly shift its focus of air surveillance and intelligence resources from Russia to the region surrounding Iran. This forced redistribution of military assets is precisely the strategic containment effect that Tehran and Moscow welcome. The resources of the superpower are inevitably tied to tactical attrition in the Persian Gulf.

The fragile Eurasian axis and the red line of precision strikes

However, this strategic Eurasian axis, fraught with peril, also carries immense physical vulnerability and the risk of backlash. To sever military and drone supply lines between Russia and Iran, Israel launched an unprecedented precision strike on the Iranian port of Anzali in the Caspian Sea. The destruction of this deep-water hub connecting the two countries not only severed a crucial logistical link but also directly crossed Moscow's security red line, forcing Russia to issue a stern warning. This action exposed the Eurasian Union's vulnerability to Western precision strikes.

Washington is caught in a profound strategic dilemma in this global war of attrition. Compromising with Tehran and lifting the maritime blockade would be tantamount to relinquishing its leverage to force Iran to completely abandon its nuclear program and allow its regime to be revitalized. Maintaining a high-intensity military blockade, however, would deplete US military inventories, while global inflation would spiral out of control with soaring oil prices, effectively continuing to fuel Russia's war machine. As the gunfire in Eastern Europe and the maritime power struggle in the Persian Gulf resonate structurally, who will bear the cost of the next systemic collapse of the future international political and economic order?
