Quite right. But it's not just the USA. A small group of industrialized countries are responsible for holding together what we call Western Civilization. Lose that and the world economy collapses by at least 90%. When the world economy collapses, the world population will also collapse. The world goes back to tribalism. That's OK for places like Afghanistan, that haven't really advanced past tribalism. But not so good for first world countries. E.g. about 99% of the jobs of HN readers will no longer exist.
