Huge amount of discussion in this thread neglects the idea that a massive increase in tariffs will throttle trade shipments. Its the obvious expected effect.

Hanlon's Razor suggests that your statement is incorrect.
Tariffs need consistency and stability to be effective rather than purely disruptive.
You can see this in how much more effective the countries applying tariffs against the US are handling things. Since they are applying tariffs and leaving them in place, the incentives are working properly, and they are disconnecting from the US businesses.
In the US, by contrast, businesses are either shutting down or holding their breath in the hopes that tariffs will pass.
It doesn't matter to someone getting the pointy end of the stick whether it happened out of malice or stupidity--the pointy end still hurts.
