Except this is about nation state behavior, context, and geopolitics spanning decades rather than some series of small unrelated events.

See my other reply. I am not excusing the behavior of treaty breaking so much as I am saying their leadership has pressure to behave in this way due to the mandate to "right historical wrongs" versus their enemies who killed and attacked them.

I am not the world's leading expert on China, history, or political science -- but I would guess that the fentanyl smuggling operations they are doing are directly related to points (1) through (5) and are some form of revenge in the eyes of their leadership. It probably isn't a coincidence that fentanyl is an opioid, is killing countless Americans, is being laced onto random pills and foods sold, and is all being done by China's intelligence agencies. You know, maybe these events are related!
