Honestly I have no problem with taking on China in general given the intellectual property theft and generally unfair trade practices that I think its pretty evident they engage in. The question has always been how do you do that, and I don't know that Tariffs are the right approach. Even if they are I don't think this has been handled well. Trump frames everything he does in a "this this guaranteed to be great for us, no downside, we re gonna win" sort of way. And Tariffs are much more of a mixed bag because although China gets hurt economically its ultimately American consumers who ultimately actually pay for the price hikes. And China was of course always gonna retaliate with their own tariffs which hurt American businesses particularly farmers. At some point I think tariffs should just be part of a bigger endgame (if used at all), a way to force concessions. I'm just not sure Trump has an exit strategy,.
I think its somewhat dangerous to be messing with our economic growth at the same time Great Britian is on path to go through a no deal Brexit. At some point so much disruption in trade has to have a ripple effect.
