What is a nuclear missile fuze?

The fuse of the atomic bomb is an ultra-precision high-explosive bomb (conventional explosive), and the composition is one in a million. If it is not well controlled, the nuclear bomb cannot be detonated, which is why the west laughs at us for not knowing how to detonate the atomic bomb.

The fuse of the hydrogen bomb is a miniature atomic bomb, because in order to make the hydrogen nucleus collide, it must be at a very high temperature to make the hydrogen nucleus reach the collision speed, and this temperature can only be achieved by the explosion of the atomic bomb.
