The United States has cited disagreements regarding Iran as the primary reason for the absence of a final document at the recent Review Conference of the Parties to the Treaty on the Non-Proliferation of Nuclear Weapons (NPT). According to US State Department spokesperson Tommy Pigott, the inability of some NPT States Parties to acknowledge Iran's perceived threats to global nonproliferation contributed to this failure. The US remains dedicated to the NPT's three pillars: nuclear disarmament, non-proliferation, and peaceful nuclear energy use. The Russian Foreign Ministry criticized the conference for lacking a balanced assessment of Iran's situation, while Iran's Permanent Mission to the UN pointed fingers at the US and its allies for the deadlock. The 11th NPT Review Conference, which took place at the UN Headquarters in New York from April 27 to May 22, involved nearly all 191 states parties and aimed to review the treaty's implementation. However, it concluded without a final document for the third consecutive time, reflecting ongoing tensions surrounding Iran's nuclear activities and international relations.
