We are screwed, that's where we are. I don't see any long-term gain from this. It will take some time, but the damage done will come to roost. The next time we need something like sanctions from another friendly country, they will hang up the phone. The economy will sputter and slide into recession because of these policies.
Pulling out of TPP was stupid. Pulling out of the Iran Nuclear deal was stupid. Siding with Putin and Israel is stupid. Denying Climate change and pulling out of the Paris accord is stupid. Asking the G7 to include Russia is stupid. Turning our backs on our allies is stupid.
China's cheap products have improved US lifestyles for a decade. It certainly isn't because of increasing wages. We should come down hard on Chinese IP theft, but tariffs are not the way to do this. Tariffs are just stupid.
To be clear, America's enemies are: Russia, Iran, North Korea and a host of terrorist organizations, not Canada, not Mexico, not Australia, not the EU and not China. China is not interfering in our elections. China is not threatening the US. China has not invaded any other countries, yet. Economics is more important to them still than being the dominant world power. That may change though. We have a lot of leverage over them even without tariffs.
