Talking to my overseas friends and family, I've noticed that they're going through the same process that people across the American political spectrum have. First curiosity, then mockery, then exasperation, then the realization that this is serious. That's when the realization begins to hit that America isn't what they thought it was.
Fortunately for them, the world has advanced enough that America is becoming less and less the indispensable country. So we're seeing new alliances form as we belligerently hide from the world. China is already ahead of us in tech and AI, and the world is now beginning to see them as a viable option.
MAGA, with its head stuck in the 1950's, doesn't see it. But a cult can go a long time existing in its separate ecosystem.
