The fascinating thing is, I talked with a couple of my friends in the US, and they think they the tariffs are going to help the US more than hurt. Paraphrasing some of the arguments, the trade war between China and the US will eventually lead to the US winning because the US is more powerful (but is it?), and then the US will have a greater share of the commodities market (possibly even a monopoly), which will stimulate domestic employment and secure their political power.
I personally agree with katgrace1. This trade war means bad news, especially since Australia relies so much on both China and the US for trade (they're our top two weights in the TWI for a reason!). The WTO hasn't been particularly effective in recent years, so we've yet to see what the collateral effect is on other countries.
