What you posted would be alright, except for political realities we now see manifesting themselves in this thread.
Political realities being that China operates in a closed political system that can take economic pain while knowing that President Trump has to deal with an open political system where economic pain could bring him down
Looks like that is what China is trying to do.
Yes, defeating President Trump in 2020 is a (perhaps the) primary goal assigned to communist Chinese propaganda and influence operations in the West. You seem to be unwittingly supporting their efforts.
They can count on many in the West, whose personal finances, or petty political preferences can be leveraged to undermine the long term interests of their nations - indeed the future freedom of the whole human race.
The hegemony that the Chinese Communist Party seeks, is one where their model of corrupt local political parties (subordinate to theirs) operate oppressive surveillance states and rigged economies, led by a small group of families who have no qualms about treating their subjects like livestock (enslaving them or harvesting their organs for personal profit) - rules throughout the world.
The assumption that they can better withstand the temporary pain of a trade conflict, is rooted in the illusion they seek to promote - that they are on roughly equal footing economically, and it would just be a marginal difference in the pain on each side.
The truth of the matter is that the USA does not particularly need China in the long run (or very much in the short run), but China runs a trade deficit with the rest of the world combined (heavily dependent on imports of oil, gas, raw materials and food), and depends on the American export markets and financing to pay their bills.
They have dramatically expanded the supply of their currency - the biggest such bubble in human history. Most of their trade is done in dollars. with significant amounts in euros and yen - but very little can be done with their currency, outside of China (which will insulate the rest of the world significantly when their bubble bursts). Their debt levels are ridiculously high, and their cash flows are precariously tight.
They might not make it to Christmas without a crisis, if Hong Kong blows, and they will be lucky to make it through 2020 otherwise. In any event, their whole economy is teetering on the edge of crisis.
