Mahamad Safa, formerly the permanent representative to the United Nations for a major human rights organization, resigned from his diplomatic positions on Friday to leak a dramatic claim, along with a desperate plea to the United States and elsewhere.“I don't think people understand the gravity of the situation as the U.N. is preparing for possible nuclear weapon use in Iran,” Safa wrote in a statement shared on social media Sunday.“I gave up my diplomatic career to leak this information. I suspended my duties so as not to be part of or a witness to this crime against humanity, in an attempt to prevent a nuclear winter before it is too late.”According to Safa, the U.N. is actively preparing for the possibility of a nuclear weapon strike on Iran. The military onslaught on Iran from both the United States and Israel using traditional weapons has yet to produce results regarding the two countries’ stated war objectives; toppling the Iranian government and removing its ability to even acquire a nuclear weapon.Traditional weapons have also failed to secure safe passage through the Strait of Hormuz – a crucial shipping channel through which 20% of the world’s oil trade flows – for U.S. and U.S.-aligned sea vessels.As such, a nuclear weapon strike remains among the few escalatory measures the United States and Israel have yet to have employed, and, according to Safa, is now actively being considered.“Yesterday, nearly ten million people protested ‘No Kings’ in the United States,” Safa continued. “The possibility of the use of nuclear weapons must be taken very seriously. It's dangerous. Act now. Spread this message worldwide. Take the streets. Protest for our humanity and future. Only the people can stop it. History will remember us.”I don't think people understand the gravity of the situation as the UN is preparing for possible nuclear weapon use in Iran.This is a picture of Tehran. For you uneducated, untraveled, never-served, warhawks licking your chops at the thought of bombing it. It's not some low… pic.twitter.com/BnzB4F3001— Mohamad Safa (@mhdksafa) March 29, 2026
