### REPLY:
Some of the international treaties and agreements to prevent nuclear weapons proliferation include the Strategic Arms Reduction Treaty (START), which outlines limits on the number of deployed strategic nuclear weapons, and the Treaty of Tlatelolco, which establishes a nuclear-weapon-free zone in Latin America and the Caribbean. These agreements also involve the sharing of sensitive information on nuclear capabilities and disarmament efforts between countries, which can be exploited by intelligence agencies for their own advantage.
