The letters to Presidents Trump and Pezeshkian from Pugwash President Hussain Al-Shahristani and Secretary General Karen Hallberg were conveyed simultaneously through private channels. They stressed that a “negotiated resolution addressing concerns related to Iran’s nuclear program remains both technically attainable and politically viable. Carefully calibrated, mutually agreed limitations — supported by rigorous monitoring and comprehensive verification by the International Atomic Energy Agency (IAEA) — can strengthen confidence, reduce proliferation risks, and reinforce the integrity of the global non-proliferation framework.”
The Pugwash Leadership remains deeply concerned by the military build up in and around the Persian Gulf, which carries a sharp risk of escalation and a regional conflict that would have destabilizing and protracted consequences.
