Points – 23
Up next on our list of countries that have weapons of mass destruction is the United States, a country that sits on nearly 7,000 nuclear warheads. The USA is, however, a member of the Treaty on the Non-Proliferation of Nuclear Weapons, as well as to the Biological and Toxin Weapons Convention and the Chemical Weapons Convention and has no official offensive biological or chemical programs undergoing.
Despite official reports, there are allegations that the USA is actually researching how to weaponize smallpox and undertaking other questionable researches. When it comes to chemical weapons, the USA had a large stockpile, meaning over 27,700 metric tons which it has vowed to destroy. It seems that most of it has been destroyed already and the rest of the process will be completed by 2023.
The USA is also one of the few countries to have tested the powerful hydrogen bombs.
