He did that temporarily with tariffs on China. Tariffs over 60% are essentially a trade embargo since thats a cost that’s too rich for companies to eat and would make imports too cost prohibitive to meaningfully compete with domestic alternatives.

Any tariff that high is a bluff. Essentially all his tariffs are a bluff, a type of ‘worst case scenario’, so that when he strikes a ‘deal’ (no matter how meaningless), he can declare victory. He’s a TV personality. Its all for show.

The working class in the US is in for some real pain. Its too bad that so many of them voted for this.
