WASHINGTON — Secretary of State Marco Rubio called Iran's negotiating demands "outrageous" and "ridiculous" at a State Department press briefing, delivering the sharpest public rejection of Iranian terms by a senior U.S. official in months and signaling a hardening of Washington's position on reviving the 2015 nuclear agreement.

Rubio's critique centers on Iran's two core demands: guarantees that a future U.S. administration would not unilaterally abandon any restored accord, and the immediate lifting of all sanctions reimposed or added since the Trump administration's 2018 withdrawal—including those targeting Iranian oil exports and the banking sector.

For the Trump administration, conceding on either point would undermine its "maximum pressure" campaign, a strategy championed by National Security Advisor John Bolton. The hardline stance aligns with pressure from conservative lawmakers. Senator Tom Cotton of Arkansas, a vocal opponent of the original Iran deal, has repeatedly urged the White House to maintain pressure on Tehran.

The public dismissal suggests the administration is betting that a firm stance will yield better terms than pursuing immediate breakthroughs. But it complicates Trump's effort to claim a foreign policy win before the election cycle while avoiding accusations of weakness from political opponents.

European allies have sunk diplomatic capital into mediating between Washington and Tehran. French President Emmanuel Macron has held multiple phone calls with President Trump and Iranian President Ebrahim Raisi in recent weeks, attempting to broker common ground. Rubio's comments indicate that gap has widened and could leave European efforts stalled.

Direct talks between U.S. and Iranian delegations are not scheduled for the immediate future. The International Atomic Energy Agency is expected to release its quarterly report on Iran's nuclear program next month, detailing uranium enrichment levels and compliance with monitoring agreements. That report could influence the urgency of future diplomatic initiatives among the P5+1 nations.
