That way, nobody would use nuclear weapons, because they could never actually "win" that way. This thought process was referred to as Mutually Assured Destruction, or MAD.
What is their defense weapons
There is no universal law that explicitly forbids the use of nuclear weapons. However, the use of nuclear weapons is regulated under international law, including the Nuclear Non-Proliferation Treaty and customary international law that limit their use to self-defense in extreme circumstances.
There is no general category for "defensive nuclear weapons" although they were once envisioned as part of an air-defense against massed bombers. The 3 letter acronym for a "defense against nuclear missiles" is ABM, which stands for Anti-Ballistic Missile defense. (There is a related acronym from the Cold War, MAD, for Mutual Assured Destruction, a policy to preclude a first strike in nuclear war by assuring the survival of retaliatory weapons.)
