“...We need a really high tariff ...”
About 800% on ALL Chinese imports, specifically.
Break their economy.
No no no no. Tariffs need to be on product classes and not against specific countries. If you tariff countries then the greedy Free Traitors™ will just move to the next 3rd world country.
If you really want to defeat China, you must first eliminate their source of power within our own country - the American politicians and the captive media they have purchased and owned for a generation. Both Democrat and Republican, they need to be forcibly removed from both position and American society outright, their media outlets forcibly closed.
China will not attack militarily, they have no ability to project power in that matter. They will use their American proxies - made unbelievably wealthy by selling out this country to China to achieve it - to rip us apart into Civil War so that we have no ability to stand against them.
