United Nations Security Council Resolution 1540

United Nations Security Council Resolution 1540, adopted in 2004, aims to prevent the spread of nuclear, chemical, and biological weapons as well as their means of delivery. It requires all countries to establish laws and measures to prevent non-state actors, like terrorists, from acquiring these weapons. Nations must also report on their efforts to strengthen security in handling dangerous materials and promote international cooperation. The resolution reflects a collective commitment to global security and non-proliferation, addressing threats that could arise from rogue states or terrorist organizations.
