I expect China, Russia, India, the US and others to lie. I expect them to steal. I expect them to sabotage. I expect them to wage economic and kinetic wars. I expect them to do everything in their power, evil or not, to give themselves an economic advantage.

Tariffs of the sort you're talking about are a great way to nudge countries in the right direction. China is already the largest polluter and is on track to double its emissions over the next decade. Stopping that will take quite a bit more than a nudge. It will take destroying their economy. Except they have nuclear weapons. I'm sorry, but we already can't get them to stop stealing our intellectual property, stop sending us products laced with lead, stop mass murder for organs, stop putting Uyghur men in concentration camps and then assigning a rapists to live with their families, stop sending fentanyl illegally the US which kills thousands every year. The idea we're going to apply enough pressure to China to turn around this boat which is going to double its CO2 emissions in the next decade seems like a complete fantasy.
