Iran Signals Intent to Escalate Nuclear Enrichment in Response to U.S. Threats

Iranian officials have indicated that the country may increase its uranium enrichment to 90% purity—a threshold sufficient for nuclear weapons—if attacked by the United States again. Ebrahim Rezaei, a lawmaker and spokesman for Iran's National Security Commission, raised this possibility in a recent post on X, stating it will be reviewed by parliament. This move comes amid heightened tensions between Iran and the U.S., with Tehran signaling a potential escalation in its nuclear program.

As of June 2025, Iran is reported to have approximately 970 pounds of uranium enriched to 60% purity, which could potentially produce enough material for about 10 nuclear weapons. Under the 2015 Joint Comprehensive Plan of Action (JCPOA), Tehran agreed to limit its enrichment levels and allow international monitoring by the International Atomic Energy Agency (IAEA). However, following the U.S. withdrawal from the deal under former President Donald Trump, Iran began enriching uranium to higher levels, including 60% purity.

The announcement by Rezaei raises concerns about the potential for further escalation in the region. If Iran were to proceed with enriching uranium to 90%, it would significantly accelerate its nuclear capabilities and bring it closer to weaponization. This development could complicate efforts to stabilize the region and undermine international nonproliferation efforts. The U.S. and its allies have repeatedly warned against such actions, emphasizing their commitment to preventing Iran from acquiring a nuclear weapon.

The situation underscores the delicate balance of power in the Middle East and the ongoing challenges of nuclear diplomacy. As parliament reviews this proposal, the outcome could have far-reaching implications for global security and U.S.-Iran relations.
