China is in the midst of a demographic collapse, and will be struggling with internal issues for decades, they're not going to be a threat. Russia is isolated and may lose most of their energy export revenues. They're not going to be a threat to anyone but their immediate neighbours. But globalization, that has been enabled by the American military, may be coming to an end. The US armed forces are retooling in a way less geared to policing global merchant shipping. This signals a likely return to more local trade, controlled by regional powers. We have been lucky to live in the richest, most prosperous era of human history. But the party seems to be winding down, and most of us and our heirs, will be living more modest lives, with reduced travel, diversity of goods, diet, and wealth.
