I was talking with two friends on discord. One(call him B) said something about Chinese troops on the Mexico and Canadian border and another (call here Y) confirm that she had heard about it. They didn't post any links about it. I just want see if there is any truth to what they said. I found it a bit farfetched because that would open up a massive can of worms.
Edit: did some looking and apparently it's old news but it's true for the Canadian border here are some articles on it.

Yeah, read one of articles I found, it said trump put f-22 and f-35 in Alaska. So I guess if they do anything they are not only having to deal with arm civilians but also air force. Overall I'm not worried, China doesn't want a physical war it would be way to costly for them.
