Nuclear Weapon - Powerful Threat to World

Nuclear war fare and nuclear weapons are the biggest threat to life on Earth. I must say that if a nuclear warfare starts, it will impact almost three-fourths of the life on the entire earth. Already some countries have pointed their nuclear missiles on their targets that range from military areas to large populated civilian areas of their rival countries. Advanced technology has aided them to detonate nuclear-wars within minutes of the decision. The largest among those are US obviously, Russia, UK and China. Other countries with fewer possibilities of firing nuclear weapons are India, France, North Korea and Pakistan. Even Israel is said to possess nuclear weapons but it is refusing to acknowledge it.

There are basically 3 types of nuclear weapons. The first one is the fission bomb which explodes through nuclear fission. These are also referred to as Atom bombs. The second type is called thermonuclear bomb which explode through nuclear fusion. These are also referred as Hydrogen bomb. The other type of nuclear bomb is boosted fission weapon with both fission and fusion reactions. We must be happy that there are only bombs and not guns which are easy to carry.
