Umm, Trump stopping trade with China won't stop China from doing business with NK. Pissing off China, South Korea and the others would only serve to isolate the US financially in the same way Trump has done politically. Another type of "wall" I suppose?
It's a matter of making it too unprofitable for China. They're not going to isolate North Korea if you don't pressure them. North Korea, as an example, pumps billions in laundered cash through Chinese banks. The US is talking about banning the four big ones from operating in the US. That's not stopping Chinese exports, that's specifically harming those doing business with North Korea. And let's face it, China has been violating every trade treaty and law for decades. The US can quite reasonably pick and choose the ones they want to start enforcing until China finally decides to arrange for the fat boy to fall off a cliff or something, and replaces him with someone more stable.
I wish I had your confidence that Trump won't try to rain down some of his "fire and fury" on Kim.
I wish I had the confidence you seem to think I had in that.
He needs to be given options which seems like they can achieve something useful (even if they don't). Cracking down on Chinese banks, as an example, combined with a renewed effort towards a missile defense shield, might do for that.
I already owned Raytheon and Harris stock. I bought Lockheed Martin today - and more gold.
I foresee much more money going into anti-missile systems.
