It is becoming more certain: Some state will use nuclear weapons

The institute claims that this could break the tendency to reduce the nuclear arsenal.
According to experts, this tendency increases the probability that a country will use nuclear weapons in war.
Since the end of the Cold War, the world's nuclear arsenal has shrunk. But that trend seems to have stopped, the SIPRI report concludes. The main conclusions are that more nuclear warheads have been deployed in operations, despite a general reduction in the number of warheads recorded by 2020. About 2.000 warheads are being held on high alert.
"This is a significant new trend, which all countries should see as a warning: we must really beware of a return to some kind of arms race between nuclear powers," SIPRI researcher Hans Christensen told Swedish national radio and television station SVT.
Between 2020 and 2021, the number of warheads in military nuclear stockpiles increased by about 300. These are nuclear weapons deployed in operational units and in military depots.
About 2/000 nuclear weapons are currently on standby around the world, most of them Russian and American weapons, according to SIPRI.
Although the United States and Russia reduced their total stockpiles of nuclear weapons by dismantling retired warheads in 2020, it is estimated that both had about 50 more nuclear warheads in the operational schedule in early 2021, according to SIPRI. The increase was carried out mainly by deploying land-based intercontinental ballistic missiles and submarine-based ballistic missiles.
However, the other seven states with nuclear weapons are also developing or deploying new weapons systems or have announced that they will do so.
For example, the United Kingdom revised its security policy in March 2021 and reversed its previous...
