Following the release of a report by the US Strategic Research Institute, Russia began to be rated as the “most real military threat” to the United States. China is now called the "most comprehensive threat." What kind of aggressive and threatening acts of the two countries is meant is not clear. However, it became known about the American development of 6.8 mm caliber bullets, that should replace the NATO 5.56 mm caliber bullets. It is weird that the development began after the publication of information about new Russian and Chinese bulletproof vests, that are resistant to the 5.56 mm bullets. So whom is aggression actually coming from and who is preparing for war?
