Mohamad Safa, a long-time representative of the Patriotic Vision Association at the United Nations, has resigned after nearly 12 years in his role, accusing the organization of preparing for the possible use of nuclear weapons in Iran. In a public statement, he said he could no longer serve while such plans were being considered and claimed he stepped down to avoid being complicit in what he described as a potential crime against humanity.

Sharing an image of Tehran, Safa stressed the human cost of any nuclear strike, pointing to the city’s population of nearly ten million people and warning of mass civilian casualties. He urged global action to prevent what he called a looming catastrophe, cautioning that nuclear conflict could trigger widespread destruction and a nuclear winter.

Safa also alleged that certain senior figures within the United Nations were serving powerful lobbying interests rather than the institution’s stated mission. His resignation comes amid reports that the United States is weighing options for possible expanded military operations in Iran, ranging from limited ground raids to broader troop deployments, even as officials publicly signal restraint.
