The proliferation of nuclear weapons and materials is a concern for many nations, leading to the drafting of the Nuclear Non-Proliferation Treaty. The development of nuclear weapons began in the 1930s and accelerated during the 1950s and 1960s. Several countries possess nuclear weapons, including non-signatories to the NPT. The concern is that nuclear weapons could lead to a bad end to a legitimate war or be obtained by terrorists. Organizations promote nuclear disarmament and peaceful applications of nuclear energy. Signatories to the NPT pledge to reduce the number of nuclear weapons in their arsenals, while some non-signatories have active nuclear weapons development programs.
Nuclear weapon proliferation is a term used to refer to the development and dissemination of nuclear weapons and associated materials such as isotopes that could be used in the production of nuclear weapons. The proliferation of nuclear materials is a concern for many nations around the world, and indeed most United Nations member states have signed up to the Nuclear Non-Proliferation Treaty (NPT) as a demonstration of a good faith desire to halt proliferation. of nuclear weapons.
As researchers realized the potential destructive force of an atomic bomb in the 1930s, the proliferation of nuclear weapons began, with the famous behind-the-scenes bomb rush during World War II culminating in the bombings of Hiroshima and Nagasaki Japan by American forces. This tremendous display of power served as an incentive for many other nations to develop nuclear weapons, and an arms race accelerated rapidly during the 1950s and 1960s as numerous countries developed nuclear weapons in an effort to keep pace with all others.
Concerns about the proliferation of nuclear weapons led to several test ban treaties in the 1960s that were designed to limit nuclear testing, and in 1968, the United Nations drafted the NPT. Five signatories to the NPT, the United States, the United Kingdom, China, France and Russia, have openly admitted to manufacturing nuclear weapons. Several non-signatories also possess nuclear weapons, including Israel, India and Pakistan, and North Korea has also been suspected of having access to nuclear weapons.
The concern with the proliferation of nuclear weapons is that it could lead to a bad end to a legitimate war if a nuclear power gets involved and decides to use its capabilities. The proliferation of nuclear weapons is also a concern for groups concerned with terrorism, as unprotected nuclear materials could potentially be obtained by terrorists. Numerous organizations have promoted nuclear disarmament, one of the goals of the NPT, and have strongly urged nations to focus on peaceful applications of nuclear energy, rather than building bombs.
The strained political relations between some of the nuclear powers have led to fluctuating policies on the proliferation of nuclear weapons. Signatories to the NPT have agreed to pledge to reduce the number of nuclear weapons in their arsenals and to halt the development of nuclear weapons to avoid perpetuating the arms race. Some nations that have not signed this agreement have active nuclear weapons development programs, and some are believed to be potentially politically unstable, which could have literally explosive consequences.
