How Multipolarity Shifts the Logic of Escalation in Iran
Rising U.S.-China-Russia rivalry dilutes Western escalation leverage, emboldening Iran’s asymmetric strategy across nuclear, drone and proxy domains, analysts say.

Iran escalation tensions surge as Russia-China axis limits US response space

Tehran’s announcement that it will expand uranium enrichment to 60% purity Monday triggered fresh warnings from Washington.
The move comes only days after President Trump threatened “all options” against the Islamic Republic when it test-fired a satellite rocket Washington says could deliver warheads.
Analysts say the crisis now plays out in a power grid that looks nothing like 2003. Moscow sells Iran air defenses. Beijing buys its oil. European capitals, hit by tariff threats from Trump, tread carefully.
Background
The United States quit the 2015 nuclear accord in 2018 and imposed unilateral sanctions that have cut Iran’s crude exports by roughly 60% to an estimated 700,000 barrels this month, according to tanker tracker Vortexa. Under the original deal, Tehran had agreed to keep enrichment below 3.67% for 15 years; the International Atomic Energy Agency documented uranium particles at 83.7% purity in January 2024, citing “limited progress” on explanations. Washington’s previous carrier strike deployment in the Gulf last summer was followed by a one-way drone attack on a commercial tanker off Oman that the Pentagon blamed on the Islamic Revolutionary Guard Corps, though no casualties were reported.
Western diplomats trace the new diplomatic geometry to 2022, when Russia began importing Iranian drones for use against Ukraine. By late 2023 the Kremlin had released captured U.S. and British tanks to Tehran for reverse-engineering and agreed to supply Su-35 fighters, according to leaked Ukrainian intelligence circulated at NATO. China signed a 25-year economic cooperation text with Iran in 2021 and has since cleared much of the country’s crude through non-transparent port storage in Dalian. “This triangular trade network erodes the coercive bite that sanctions used to deliver,” Richard Goldberg, a former aide to the Trump administration, wrote in the National Interest last month.
What’s Next
Republican senators plan to attach a repeal measure to the looming National Defense Authorization Act that would nullify a 2024 entity list waiver allowing Chinese refiners to handle Iranian oil—action that continues bipartisan negotiations. European officials will seek IAEA board censure against Iran at consensus talks scheduled for June, though diplomats acknowledge Russia can block a formal referral to the Security Council. Trump hinted in a Fox interview Sunday that he could act “as fast as Tuesday,” raising Pentagon speculation of an accelerated bomber tasking window early in July.
A multipolar plaza now frames Tehran’s nuclear calculus, frustrating the old playbook of escalating sanctions and strikes that once narrowed a rogue state’s choices. With Russian air defenses scheduled for delivery this quarter and Chinese insurance covering the barrels that keep Iran’s treasury breathing, the West finds itself staring at a market of pressure points reduced by roughly half since Dick Cheney last floated a bombing sortie. Future flash-points may pivot less on uranium percentages and more on who disables whose fuel shipments first in the Strait of Hormuz—still the artery for one in five barrels of global trade.
