Abstract
The nuclear proliferation is associated with the spread of nuclear weapons, fissile material, and weapon-applicable nuclear technology and information, to nations, that are not recognized as 'nuclear weapon States' by the Nuclear Non-Proliferation Treaty (NPT). Indeed, with the end of the Cold war, the threat of a nuclear conflict has not vanished. On the contrary, the 21st century seems an even more dangerous, because it will be a less predictable era. The global stockpile of nuclear weapons has reduced, but the chance that someone, somewhere might detonate a bomb is higher. In addition to that, more and more countries, and probably terrorist groups are eager to develop a nuclear capacity.
