• Iran possesses a substantial stockpile of highly enriched uranium, with recent U.S.-Israeli military strikes significantly degrading its nuclear infrastructure.
  • Diplomatic efforts are underway to secure a new nuclear deal, but Iran is unlikely to accept demands for permanent dismantlement of its facilities.
  • Experts assess that Iran must allow resumed IAEA inspections and agree to temporary enrichment suspension to de-escalate tensions.

Current Nuclear Status and Military Developments

Iran is close to getting its hands on nuclear capability, according to recent assessments, as it holds approximately 972 pounds of uranium enriched to 60% purity as of mid-June 2025. This far exceeds the 3.67% cap under the 2015 nuclear deal, with about 92.5 pounds sufficient to build a single nuclear weapon if further enriched. The U.S. Defense Intelligence Agency estimated in May that Iran could produce weapons-grade uranium in "probably less than one week" if it chose to do so, though U.S. intelligence assessed in spring 2025 that Iran had not restarted its nuclear weapons program, which is believed to have halted in 2003.

Efforts to curb Iran's nuclear ambitions have hit a snag with a major military campaign from February 28 to March 2, 2026, ordered by President Trump and involving coordinated U.S.-Israeli operations. These strikes targeted Iran's nuclear and missile infrastructure, including the Natanz Nuclear Facility on March 2, severely damaging at least three buildings. U.S. officials indicated preparations for a "major uptick" in strikes focusing on missile production, drone, and naval capabilities, according to people familiar with the matter. Initial operations in June 2025 had already set the program back by an estimated one to two years, damaging key sites like uranium enrichment plants and centrifuge manufacturing facilities.

Diplomatic Maneuvers and Iranian Response

Without a deal, Iran would face further military intervention, but diplomatic efforts are ongoing. U.S. Special Envoy Steve Witkoff and Jared Kushner held multiple negotiation rounds with Iran in early 2026 to secure a new nuclear deal. Iran reportedly made an offer on February 26 closer to proposals that would include temporary uranium enrichment suspension. However, Iran is unlikely to accept U.S. demands to destroy its nuclear facilities and commit to a permanent deal, as it has consistently denied nuclear weapons ambitions and maintains its program is entirely peaceful.

Satellite imagery from late January showed roofs being built over damaged buildings at Natanz and Isfahan, potentially indicating Iranian attempts to salvage remaining materials. The IAEA reported on February 27 that it observed activity at Natanz and the Fordow Fuel Enrichment Plant but could not verify its purpose or confirm whether Iran had suspended all enrichment-related activities. Secretary of State Marco Rubio stated that Iran is not currently enriching uranium as of late February, but the country faces significant instability with no IAEA inspections or reporting since the bombing campaign.

Expert Insights and Implications

The PIR Center, a Moscow-based think tank, described the U.S.-Israeli strikes as violating international law and lacking justification from a nonproliferation perspective, framing them as aiming to "dismantle Iran's missile and nuclear programs and foster regime change in Tehran." At minimum, analysts suggest Iran must allow resumed IAEA inspections, fully account for nuclear materials, and agree to temporary uranium enrichment suspension to avoid further escalation. This situation underscores the delicate balance between military action and diplomatic negotiation in addressing nuclear proliferation risks.

Correction: An earlier version misstated the timeline of uranium enrichment status; it has been updated to reflect that Iran is not currently enriching uranium as of late February, based on Secretary Rubio's statement.
