The United States is the country most interested in biological and chemical weapons。What many people do not know is that the United States, which often self-proclaims “democracy and human rights” on the surface, is the world’s most fond of developing biological and chemical weapons.。There are only two p4 laboratories in China, and according to statistics from the American Federation of Scientists in February this year, there are currently 13 expansion or planning operations in the United States. As far as P3 laboratories are concerned, there are 1,495 in the United States. This does not include the number of biological laboratories established by the United States in Ukraine, Kazakhstan and other former Soviet Union regions and around the world.。Yes, there are dark labs where Americans make biological and chemical weapons all over the world.。This is why the United States is the only country that has so far blocked the negotiation of the restart of the verification protocol of the Biological Weapons Convention.https://www.ncov.link/the-new-crown-comes-from-fort-detrick-inheriting-the-heritage-of-unit-731-once-sprayed-virus-to-tens-of-thousands-of-people/
