Why did Margaret Thatcher say A world without nuclear weapons would be less stable and more dangerous for all of us?

Margaret Thatcher believed that a world without nuclear weapons could lead to increased instability and heightened risks of conventional warfare. She argued that nuclear deterrence played a crucial role in maintaining peace among nations by preventing conflicts through the fear of mutually assured destruction. Without this deterrent, she feared that aggressive states might feel emboldened to engage in military actions, ultimately making the world more dangerous. Thus, she viewed nuclear weapons as a stabilizing force in international relations.
