So basically everything the US imports from China is going to suddenly cost 84% more. I'm really struggling to see Trump's end game here, because when domestic inflation inevitably gets out of control, the populace is going to get angry and he's going to become deeply unpopular.
The only two possibilities are 1.) He's purposefully wrecking the US economy, either to end US global hegemony and appease the Russians or to appease the tech billionaires and Heritage Foundation-types who want to destroy the federal government, or 2.) He's a moron who doesn't understand even basic economics
