What Would Happen to the World Without the US?

What would happen if the United States collapsed right now? At first, Mexico would seize the opportunity to launch a massive invasion to the north, aiming to revive its old empire and reclaim lost territories. At the same time, Canada would move quickly to take revenge on all the bullies and occupy key strategic areas in the south. However, Russia wouldn't just sit back. They would immediately launch a massive invasion to retake Alaska, ensuring it is never sold again. Meanwhile, in the Middle East, Iran would instantly launch a devastating military operation on Israel. Without American support, an isolated Israel would face total collapse in a matter of days. In East Asia, China would launch a full-scale invasion of Taiwan while joining forces with North Korea to open a new front against the south, aiming to unify the entire Korean Peninsula. Shocked by this rapid escalation, Japan would have no choice but to immediately remilitarize to defend its own national security. Further south, without the U.S. Navy to stop them, China would become increasingly aggressive in the South China Sea, threatening the sovereignty of nations like the Philippines and Indonesia. Finally, without American leadership, NATO would crumble, leaving Europe completely vulnerable. Seeing this weakness, Russia would expand its invasion of Ukraine and ramp up pressure on Eastern Europe, ultimately proving that a world without America is a world at war.
