Various aspects of the US-Canada tariff war?

Disclaimer
-----------------------------------
It originally started with the US-China hegemony competition....
When things didn't go Trump's way... he attacked Canada, a weak link among his allies...
It is not just the US; all past hegemonic powers have acted this way...
Attacking the weak link is a phenomenon seen in the world of organized crime and gangsters.
Trump and the far-right are engaged in a petty struggle...
Trump is enraged that China is exporting via bypass routes like Canada.
He wants Japanese auto plants to be built within the US, and he is enraged again because they are trying to seek tariff benefits through Canada.
Trump is targeting Canada, Japan... and China.
