In 2004, the UN Security Council recognised that the proliferation of nuclear, chemical and biological weapons and their means of delivery constitutes a threat to international peace and security. While common discourse has generally normalised the existence and purpose of nuclear weapons, a growing movement within international relations is calling for a world without them. Is a new normal under construction? María Antonieta Jáquez, counsellor at the permanent mission of Mexico to the UN and member of the Mexican foreign service since 1994, tells Olga and Hugh that this is already the norm for most of the world. In fact, the shift against nuclear proliferation gained traction as early as the 1960s, underpinned by principles of international humanitarian law and embodied in the Treaty on the Non-Proliferation of Nuclear Weapons (NPT). While 116 countries have signed such treaties since then, the question remains: have nuclear weapons really deterred wars? Jáquez makes the case for global disarmament and shares what inspires her diplomatic efforts to bring about a new reality in a field often too preoccupied with theories of deterrence and power projection.
