JERUSALEM — A leading U.S. research institute devoted to monitoring Iran’s illicit nuclear weapons program published an alarming report ahead of this weekend’s U.S.-Iran talks, declaring Tehran’s atomic weapons system has reached an extremely dangerous stage.

The Washington, D.C.-based Institute for Science and International Security titled its shocking new report, “The Iran Threat Geiger Counter: Extreme Danger Grows.” 

According to the study, “Since February 2024, the date of its last report, the threat posed by Iran’s nuclear program has worsened significantly. Major negative factors include Iran’s greater nuclear weapon capabilities, its shorter time frames to build nuclear weapons, and the growing normalization of internal Iranian discussions favoring building nuclear weapons.

A state-controlled Iranian news outlet claimed on Monday that Iranian Supreme Leader Ali Khamenei’s alleged fatwa against nuclear weapons does not outlaw their production but bans their use. Fox News Digital sought to obtain a copy of the alleged religious fatwa from Iran, but the regime has so far refused to provide the document. Iran experts have claimed that the fatwa is non-existent. 

The Institute for Science and International Security report also warned that “Iran still possesses military capabilities that threaten the region. It has large stockpiles of drones, ballistic missiles, and cruise missiles that it can employ against Israel and its allies. Iran also continues to be a major player in the Ukraine war, backing Russia with vast arms transfers, including drones and missiles.”

The mouthpiece of Iran’s Khamenei—the anti-American paper Kayhan—just urged the assassination of Trump.

A State Department spokesperson told Fox News Digital that “Threatening language from the Iranian regime or its mouthpiece against the President, or any American, is unwise.”

Iran’s regime has sought to assassinate Iranian American dissidents on American soil.
