And then you'll enjoy more experiences of aggressively-expansionist governments, Houthi-like groups, and the equivalent of Haitian gangs and Sudanese militias, all over the world, fighting to advance their leaders' own narrow parochial desires wherever they think they can get away with it. They'll be using WhatsApp, Starlink, and cheap drones in their efforts, and enlisting like-minded allies.
You'll find yourself looking back wistfully on the days of the Pax Americana, which for nearly 80 years has maintained a flawed but workable rules-based international order. That's even granting that the U.S. has done some bad things — on occasion, very bad things — in furtherance of its own perceived interests and those of some of its powerful interest groups.
