Basically, Trump administration is "punishing" China, Iran etc by hurting its own allies: Canada, Mexico... UK, Australia... Japan (>oil from Iran).
I wanted to include EU to the list, but it is already on US "enemy" list. :D
If "miracle deal" wil not happen at G20 (next weeks), UK will be hurt the most, IMHO. Not just because of Vodaphone 5G. Trump colud be gone at 2020, but China will not trust UK anymore (and UK will not be part of EU market, probably).
Pretty much desperate future.
