Me upset? About the facts? You are the upset one, not me.
I don't know if you consider turning a flourishing economy into a trainwreck within months like Trump did a success, but if you do, you may want to look up that term in a dictionary.
And while you are at it, you might want to look up some facts about the economical developments of the USA and China as well.
It takes more to piss off China than an inept president. If China had been really pissed they would just divert the goods manufactured for US companies elsewhere or close these factories or whatever.
China can cope with the losses. The USA after four years of Trump, not so much.
Oh, and don't forget India, the EU and to a lesser extent Russia. While Trump has diminished America, the economies of these zones grew stronger and especially more independent from the USA.
In a nutshell and probably to your dismay: Trump has completely blown it. Throroughly.
