Nuclear triad
Israel is known to have nuclear-capable aircraft and land-base missiles, with the addition of nuclear-armed submarines this would mean that they now have a full triad of land-, air-, and sea-based nuclear delivery systems some of which would be invulnerable to a first strike by an enemy for the first time in their country's history. No other nation in the Middle East in known to be in possession of nuclear weapons, even though Iran, Iraq, Syria and Libya have started development programs that were never completed.
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.
