Nuclear Brinkmanship: Iran Threatens 90% Uranium Enrichment if US-Israeli Attacks Resume

The Iranian Parliament has issued a stern warning that it could move to 90% uranium enrichment—the level required for nuclear weapons—if the United States or Israel launch any further attacks on its territory. The Nuclear Ultimatum Ebrahim Rezaei, spokesperson for Iran’s National Security and Foreign Policy Commission, stated today that "one of Iran's options in the event of another attack could be 90% enrichment." This marks a significant escalation in rhetoric as the country's nuclear doctrine undergoes parliamentary review.

Nuclear Brinkmanship: Iran Threatens 90% Uranium Enrichment if US-Israeli Attacks Resume

In a significant escalation of nuclear rhetoric, the Iranian Parliament has warned that it may authorize 90% uranium enrichment—the threshold for weapons-grade material—should the U.S. or Israel launch a new offensive against Iranian territory.

The Nuclear Ultimatum

Ebrahim Rezaei, spokesperson for Iran’s National Security and Foreign Policy Committee, announced via social media that the parliament is prepared to review the country’s nuclear doctrine. This move signals a potential shift from Iran’s current enrichment levels to the purity required for a nuclear warhead, framed as a direct response to external military threats.

Fragile Diplomacy in 2026

The threat comes at a time of extreme regional instability following a series of major events earlier this year:

  • The February Escalation: Massive strikes by the U.S. and Israel on February 28 led to Iranian counter-attacks across the Gulf and the strategic closure of the Strait of Hormuz.

  • Failed Mediations: A Pakistani-brokered ceasefire was established on April 8, but high-stakes negotiations in Islamabad have struggled to reach a permanent peace deal.

  • The Trump Factor: While President Donald Trump extended the truce indefinitely, he recently rejected Iran's latest 14-point peace proposal, labeling it "totally unacceptable."

Strategic Implications

Iran’s warning serves as a "deterrence signal" to the West. By putting the 90% enrichment option on the table, Tehran is leveraging its nuclear technical capacity to discourage a resumption of the kinetic war that paralyzed global energy markets earlier this spring.
