Re: War or Commerce?
From Nixon and until Trump, the US policy on China has been about engagement. US universities are awash with Chinese students - have you reviewed the doctoral science programs at CalTech? The current Chinese president was educated in the mid-west and got his mercantile experience selling agricultural hardware there.
In that time, thanks largely due to the US accommodating massively lop sided trade with China, the middle kingdom has begun to lift itself out of self-inflicted poverty. Good for them. But not so good for US citizens. Sure, they get cheaper products but have lost or have never invested industries that employ millions. Great for those living in cities and greater metro areas. Not so good for the vast numbers living in actual poverty in rural USA. And US voting patterns bear this out.
There is no easy solution. But just spouting sentiments like let's go easy on the Chinese is not a solution either. It's virtue signalling to like minded people who also live in big cities.
I recommend you read "From third world to first" by Lee Kuan Yew, one of the founders of modern Singapore. Although written nearly 20 years ago its still worth the effort. Ethnically chinese (Fujian province) he recounts many meetings with Chinese leaders over his four decades as prime minister and from these explains why it is that he believes China cannot be trusted to be a good international citizen. Again, this is not some western academic. It is someone who grew up in south east asia and who watched China implode under Mao Zedong then begin to claw its way back. He repeatedly points to the cultural Confusianism of the Chinese and the likely effect of that culture on the way China will develop.
So far, his predictions have been on the money. If they continue to be correct, they don't describe a pretty outcome for the US or the west in general or south east asia in particular.
