tbh if the US continues down this path long term, forcing other nations to self innovate, and if the US does not import cheaper goods/ideas, then the US will enable its competitors to catch up. really dumb.
I wouldn't say they are dumb. But it is inevitable they have to go down this route because they have no choice really.
The only other choice is have a proper World War and I can obviously tell you they will be confident. If you ask anyone on Pard, they will tell you 200% that US will win.
Once they win the war they will just re calibrate the entire global system again.
If they win or to some ...when they win.
