Security Council Resolution 1540

Security Council Resolution 1540, adopted in 2004, requires all countries to prevent non-state actors, like terrorists or criminal groups, from acquiring or using weapons of mass destruction (such as nuclear, chemical, or biological weapons). It mandates nations to establish laws, controls, and oversight to secure sensitive materials and related technologies. The resolution aims to enhance global security by ensuring that these dangerous materials do not fall into the wrong hands, reducing the risk of catastrophic attacks. It emphasizes international cooperation, transparency, and accountability to strengthen collective efforts against weapons proliferation.
