Andrea Stricker, Deputy Director and Research Fellow at the Foundation for Defense of Democracies (FDD), issued a stark warning this week: Iran will not produce a sound nuclear deal through short-term “confidence building” measures — including the unfreezing of assets or the removal of U.S. forces from the region. In a detailed thread posted to X, Stricker outlined exactly what a credible, verifiable nuclear agreement with Tehran must require.

Stricker’s commentary arrives as diplomatic back-channels between Washington and Tehran remain active, with reports of preliminary frameworks involving phased sanctions relief in exchange for temporary enrichment pauses. For Stricker and FDD’s nonproliferation team, such frameworks represent a fundamental misreading of what constitutes genuine nuclear rollback — and what Iran has historically been willing to concede.

Stricker laid out a precise, multi-point framework for what any genuine Iran nuclear agreement must entail — going well beyond caps on enrichment levels or short-term inspections. The requirements, she argued, must be implemented under full international supervision and verification:

Stricker was unequivocal about the consequences of accepting a lesser deal: “That is what a genuine deal looks like, and how a state behaves when it has verifiably abandoned the pursuit of nuclear weapons. Anything short of this is not worth sanctions relief, lifting the blockade, or ceasing the conflict.”

The warning is particularly pointed given Iran’s current nuclear posture. According to the International Atomic Energy Agency (IAEA), Iran has accumulated significant stockpiles of enriched uranium at levels far exceeding those permitted under the 2015 Joint Comprehensive Plan of Action (JCPOA) — a deal the United States withdrew from in 2018 and which Iran progressively abandoned in response. The 60% HEU stockpile Stricker references sits just below weapons-grade (90%) and represents one of the most proliferation-sensitive accumulations ever permitted to persist under nominal diplomatic engagement.

The underground facilities Stricker names — including what analysts call the Pickaxe Mountain facility, believed to be a deeply buried enrichment site in development — underscore the urgency: any agreement that leaves hardened, subterranean infrastructure intact provides Iran with a rapid reconstitution capability that renders surface-level inspections insufficient.

Folks, I feel like a broken record, but Iran won’t reach a sound nuclear deal after 30 days of so-called “confidence building” (i.e., bribery via unfrozen assets), nor after removal of U.S. forces. A credible nuclear deal must include Iran’s commitment to the following, under full supervision and verification:

Recovery and export of all 9,000+ kg of Iran’s UF6 stocks — including the 440 kg of 60% HEU — currently entombed in Esfahan, Natanz, and Fordow.

Full and permanent dismantlement, export, or in-place destruction of Iran’s uranium enrichment assets, including centrifuges, related components, and all centrifuge manufacturing capabilities.

A permanent ban on uranium enrichment and reprocessing.

Dismantlement or destruction of all nuclear facilities tied to the above programs, including underground sites such as the Esfahan tunnel enrichment plant and the Pickaxe Mountain facility.

A complete, accurate, and comprehensive Iranian declaration of its entire nuclear program — including all past nuclear weapons-related work — along with verified termination of any weaponization efforts.

Anywhere, anytime IAEA inspections — including at military sites — along with full access to equipment, personnel, and documentation.

That is what a genuine deal looks like. Anything short of this is not worth sanctions relief, lifting the blockade, or ceasing the conflict.
