A couple of things come to mind here. The ABM stuff is actually a perfect example of this. We funnel money into one group of government contractors to protect us. If it works, then we feel safer. If it doesn't, then we get to spend more money. Meanwhile, we've somehow gotten the idea that we should keep spending money on it despite the fact that it doesn't work. But there does seem to be an attempt by Trump&Co. to work us up over N. Korea. The problem is that they've pissed off everyone who would actually make this possible: the press and the intelligence community. The only question now is who's going to be bit on the ass by this first: us or him. Sorta, and I'm inclined to agree. But your phrasing it as a global split is kind of a reminder: our one country is basically the size and population of Europe with probably more cultural diversity. It's natural that things are going to be chaotic, and that's how things were set up: we're actually doing the much harder thing IMO.Korea and nukyoolar missiles.
