Nuclear weapons debate
After the bombings of Hiroshima and Nagasaki, the world’s nuclear weapons stockpiles grew, and nuclear weapons have been detonated on over two thousand occasions for testing and demonstration purposes. Countries known to have detonated nuclear weapons—and that acknowledge possessing such weapons—are (chronologically): the United States, the Soviet Union (succeeded as a nuclear power by Russia), the United Kingdom, France, the People's Republic of China, India, Pakistan, and North Korea.
Bulletin of the Atomic Scientists
Although the arms race and the Cold War, which were focuses of the "Bulletin" for many of the earlier years, are no longer occurring, the publication still focuses on the nuclear dangers that exist in the world today. As more countries such as Pakistan and India have tested nuclear weapons, the "Bulletin" has focused on the dangers posed by these countries. The "Bulletin's" bi-monthly "Nuclear Notebook" is written by Federation of American Scientists experts Hans Kristensen and Matt Korda and tracks the number of nuclear weapons in the world by country. Robert "Stan" Norris, who was a founding co-author of the Nuclear Notebook, retired from the Notebook in 2018, although he is still a senior fellow at FAS. In 2015, the "Bulletin" added the Nuclear Notebook Interactive, an infographic that illustrates which countries have nuclear weapons and when they got them, and how many nuclear warheads they have in any given year. All nine nuclear-armed states are featured: the United States, Russia, China, India, Pakistan, France, Britain, Israel, and North Korea.
