It has crossed my mind but would they risk the massive retaliation it would bring upon their heads if it was found out they did it
Honestly? From what I gather from the Chinese people I live amongst, I think they believe that we are truly stupid. And are they right? They live here and watch our ridiculous political infighting that goes on and on. Why couldn't they release a virus on us that will scare most of our population, possibly overwhelm our healthcare system, and just sit back and watch us burn?
Maybe. Invasion of the US would never work. It has to be subversion in some form. Their best way is to prop up people like Bernie and AOC. Economic collapse of the USA is DOOM for most everyone else.
If your going to release a pathogen on purpose it is going to be designed to kill a hell of lot more than 1%.
You are exactly right except for one detail. It doesn't matter which democrat anymore they are all horrible for our country.
