The report said that these data were released at a time when the Biden administration was trying to restart arms control negotiations with Russia.
It is reported that as of September 30, 2020, the US military had 3750 active and non active nuclear warheads, a year-on-year decrease of 55 and 72 compared with the same period in 2017. This figure is also the lowest since the peak of the U.S. nuclear arsenal at the height of the cold war between the United States and Russia in 1967, when the total number of U.S. nuclear warheads was 31255.
According to reports, the U.S. State Department said in a statement: "improving the transparency of national nuclear reserves is crucial to preventing nuclear proliferation and reducing armaments."
According to foreign media reports, the annual report released by the Stockholm International Peace Research Institute on June 14 said that by the beginning of 2021, there will be about 13000 nuclear weapons left in the world, and the United States and Russia still account for more than 90%. The researchers also believe that the reduction of nuclear arsenals since the early 1990s seems to have stalled, and there are signs that the number of nuclear weapons deployed has increased.
