As warheads proliferate, decades old nuclear weapons treaty must evolve, warns UN chief

The UN Secretary-General warned that the 1970 Treaty on the Non-Proliferation of Nuclear Weapons must evolve to survive the age of AI and other new technologies. The number of nuclear warheads is on the rise, and global military spending jumped to $2.7 trillion in 2025.
The UN Secretary-General, António Guterres, warned that the 1970 Treaty on the Non-Proliferation of Nuclear Weapons (NPT) must evolve to address new technologies like artificial intelligence. The number of nuclear warheads is rising, and global military spending reached $2.7 trillion in 2025. Guterres emphasized that humanity must never cede control over nuclear weapons until they are eliminated. The NPT Review Conference is underway at UN Headquarters, with the President of the Review, Do Hung Viet, echoing Guterres' warnings. Viet stated that the treaty's relevance and credibility are under threat, and a nuclear arms race is looming. The conference is facing challenges, including objections to Iran's candidacy for a leadership position, with the US and other countries citing Iran's nuclear program as a concern.
