In the process of development over the past 50 years, the nuclear bomb has become the ultimate weapon on the earth. The atomic bomb was developed during the Second World War of the Manhattan Project and was successfully tested in New Mexico on July 16, 1945. At this point, nuclear weapons have been changed from final weapons to political weapons. America decided to use atomic bombs to break Japan to save the lives of about 500,000 American soldiers needed to end the war. In the summer of 1945, the United States dropped two bombs in Hiroshima and Nagasaki.
Nuclear proliferation is a nuclear weapon, and information on nuclear technology and fissile material and applicable weapons is spread to countries that are not recognized as "nuclear - weapon states" by the Nuclear Non - Proliferation Treaty (NPT). "Non-proliferation Treaty" Many countries, with or without nuclear weapons, are concerned that nuclear weapons holders will increase the possibility of nuclear war, so many countries oppose nuclear proliferation with or without nuclear weapons . State Sovereign Relationship or Violation
Nuclear proliferation is used to explain the proliferation of nuclear weapons and relevant weapons' nuclear technology and information to countries that are not recognized as "nuclear - weapon states" by the Nuclear Non - Proliferation Treaty It is a term. Convention or NPT. One of the criticisms of the Treaty on Non - Proliferation of Nuclear Weapons is that it is discriminatory to have nuclear weapons tried before 1968 and other countries that have joined the treaty to abolish nuclear weapons as nuclear - weapon states.
After more than 70 years of development and use during the Second World War, nuclear weapons are still the basis of national security policies in many countries. The Nuclear Nonproliferation Treaty (NPT) prohibits non - nuclear - weapon states from developing nuclear weapons. However, the Nuclear Non-Proliferation Treaty abandoned the ban on five legal nuclear-weapon states (France, People's Republic of China, Russian Federation, the United Kingdom and the United States of America). Before the treaty was negotiated in 1968, the five countries were testing nuclear weapons. However, this "exemption" is inconsistent with the full disarmament with the legal obligations of the five nuclear-weapon states, Article 6 of the Treaty on Non-Proliferation of Nuclear Weapons. Three other nuclear-weapon states, India, Israel and Pakistan have never joined the Treaty on Non-Proliferation of Nuclear Weapons but have nuclear weapons. North Korea withdrew from the "Non-Proliferation Treaty" in 2003. Despite international condemnation and sanctions, North Korea's nuclear test has been repeated over and over since 2006.
