SIPRI - Trends in world nuclearforces, 2018
IPRISIPRI’s annual nuclear forces data shows that while the overall number of nuclear weapons in the world continues to decline, all of the nuclear weapon-possessing states are maintaining and modernizing their nuclear arsenals. At the start of 2018 nine states—the United States, Russia, the United Kingdom, France, China, India, Pakistan, Israel and the Democratic People’s Republic of Korea (North Korea)—possessed approximately 14 465 nuclear weapons.
