The Stockholm International Peace Research Institute (SIPRI) launches the findings of SIPRI Yearbook 2018, which assesses the current state of armaments, disarmament and international security.
Key findings include the following:
1. All the nuclear weapon-possessing states are developing new nuclear weapon systems and modernizing their existing systems;
2. The number of personnel deployed with peace operations worldwide continues to fall while the demand is increasing.
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. This marked a decrease from the approximately 14 935 nuclear weapons that SIPRI estimated these states possessed at the beginning of 2017.
The decrease in the overall number of nuclear weapons in the world is due mainly to Russia and the USA—which together still account for nearly 92% of all nuclear weapons—further reducing their strategic nuclear forces pursuant to the implementation of the 2010 Treaty on Measures for the Further Reduction and Limitation of Strategic Offensive Arms.
