Which treaty was ratified to enhance international security in 2025?

The Comprehensive Nuclear-Test-Ban Treaty (CTBT) was ratified in 2025 to enhance international security, primarily by prohibiting all nuclear explosions for both civilian and military purposes. This treaty contributes to global stability by helping to prevent the proliferation of nuclear weapons and fostering an environment of trust and cooperation among nations. As countries commit to not conducting nuclear tests, it lays the groundwork for disarmament and the reduction of nuclear arsenals, thus playing a crucial role in enhancing international security.

In contrast, the Treaty on the Prohibition of Nuclear Weapons specifically focuses on the total abolition of nuclear weapons, while the Paris Agreement is primarily aimed at addressing climate change issues. The Arms Trade Treaty regulates international trade in conventional weapons but doesn't specifically pertain to nuclear arms testing. Each of these treaties has its significance, but the CTBT directly addresses the issue of nuclear testing, aligning more closely with the goal of enhancing international security.
