What are Nuclear Weapons?

Nuclear weapons are very strong bombs that get their power from nuclear reactions. They can be made in two ways:

Fission bombs (atomic bombs): These use the splitting of atoms to release energy.
Fusion bombs (hydrogen bombs): These join atoms together and are even more powerful than fission bombs.

These weapons can kill millions of people and damage the environment badly.

Later, India and Pakistan built them too, even though they were not part of the NPT.
