What I'm saying is that using US tariff against other nations is assured to stifle global economy and US can't thrive in isolation while his tariff plunges other countries into or near recession.
Fact is he is dreaming that his tariff works only unilaterally, in fact it will work against US interests in more ways than just a retaliatory tariff, it will also encourage a backlash via boycott of US goods and discourage countries from buying US Treasuries making them dearer to raise funds.
When other countries already reeling from poor economic outlook gets hit with his tariff, it will put pressure on those countries residents and businesses and dampen their consumption for goods including US goods.
The amount of net tariff positive outcome that Trump can get won't be sufficient to fund the sort of tax cuts that he had hoped for, unless he resorts to even more draconian measures including plunder.
