I read a dozen books on post-Nixon US politics.
The amount of allegations from both sides of US politics that the other benefitted in the personal capacity from trade with China is staggering.
At least some of them must be genuine.
It comes to a very simple explanation that communists have indeed been influencing US politics for decades with very crude means, and that they were successful in that.
This is an embarrassing admission US has to do first before any recovery can be started.
