You're completely right. The "trade war" is something that came out of Trump's sick mind, influenced by Bannon. Not only a trade war is stupid, because it hurts the US economy, it is also morally unjustified: the US has spent the last 100 years or more preaching open markets. The thing that makes me more sick is seeing that the US-based media buys the whole argument and runs with it without critically analyzing what they're doing. In fact the biggest power Trump has is to plant an idea in the minds of journalists and let them run and expand on that idea without ever criticizing what they're doing.
"The "trade war" is something that came out of Trump's sick mind, influenced by Bannon."
This is incorrect. Peter Navarro is the main driver for addressing China's practices. He wrote the book on it.
"it is also morally unjustified: the US has spent the last 100 years or more preaching open markets."
China's markets are not open? How many foreign companies had to do 51/49 split ventures to access Chinese markets? Do you think they wanted do that? Do you honestly think that is 'open'?
