This is all very complex and I'm having a hard time seeing the big picture. There's trade wars, US foreign policy on North Korea (China plays a significant role), and over the last few years a ramping up of discussions on how to avoid the Thucydides trap. It's worth noting here that China and Russia, and potentially Iran are allies. All these things are connected in complex ways and while it's important to look at an issue like the trade war in isolation, I think it's also important to view it in context. And that big picture context is something I'm having a very hard time pulling together. Can anyone recommend some reading that would illuminate this?
