The world does not need more nuclear weapons

Let's strart with a definition of a nuclear weapon.

Nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission or a combination of fission and fusion. Both reactions release vast quantities of energy from relatively small amounts of matter.



Ok, so lets see which countries have the biggest nuclear arsenals.



Today nine nations collectively control more than 15 000 nuclear weapons, each hundreds of times more powerful than those dropped on Nagasaki and Hiroshima. According to Erika Gregory, we don't need more nuclear weapons but we need a new generation to face the unfinished challenge of disarmament stated decades ago. Nuclear reformer Erika Gregory calls on today's risig leaders- those born in a time without Cold War fears and duck-and-cover training- to pursue an ambitious goal: ridding the world of nuclear weapons by 2045.
