The Nuclear Security Summit is an international meeting aimed at preventing nuclear terrorism and enhancing global nuclear security. It brings together world leaders, experts, and organizations to discuss strategies for securing nuclear materials and facilities. The summit emphasizes cooperation among nations to reduce the risk of nuclear weapons falling into the hands of terrorists. Initiated in 2010 by President Barack Obama, the summit has led to significant commitments from participating countries to improve their nuclear security measures. The discussions often focus on best practices, sharing information, and strengthening international agreements related to nuclear safety and non-proliferation, involving organizations like the International Atomic Energy Agency (IAEA).
