Just had a thought.
There is one thing Trump can do to hurt China. If he could make the Chinese build of Microsoft Windows stop working, he could totally wreck a lot of China's civilian computing ecosystem. It would be easy for Microsoft to break Windows selectively, in China only: Windows 10's automatic "upgrade" process is perfect for injecting viruses.
And lose the entire industry?
The number of assasins sent by the lobbyists and businessmen will outnumber Trump’s inauguration crowd. And Trump being stabbed to death by the entire senate is the BEST outcome here.
If it somehow happens, America would never sell a product again, not unless they regime change, change the flag and give it a few decades. The number of jobs and lives lost would make the Great Leap Forward look like a golden harvest in comparison.
