The US is adopting isolationist policies based on a nationalist ideology. The government is run by anti-intellectuals. The US economic policy is based on xitter rants, and flip-flops every week. The fickle vindictive ruler is personally attacking businesses that don't make him look good. It's clear that in the US the path to success is now loyalty. The president runs a memecoin.
It is not going to happen, this is just day-dreaming. Yes, I saw the news, but you can't compare a few tens of people wanting to leave the US for ideological reasons to millions of people that stay in the US because they can fare better and make more money or start new companies overnight because they have a great idea.
The US is not adopting isolationist policies. It's adopting more nationalistic policies, which is no different than how China has been running its economy (and politics in general) for decades. And specifically the four year Trump Administration is pursuing heavily nationalistic policies. There's no evidence the Democrats will keep much of Trump's policy direction, as certainly the Biden Admin and Trump Admin could hardly be more different.
Let me know where you see the US military pulling back from its global footprint. How many hundreds of global bases has the US begun closing? They're expanding US military spending as usual, not shrinking. The US isn't shuttering its military bases in Europe or Asia.
The US is currently trying to expedite an end to the Ukraine v Russia war, so it can pivot all of its resources to the last target standing in the Middle East: Iran. That's anything but isolationist.
Also, the US pursuing Greenland and the Panama Canal, is the opposite of isolationist. It's expansionist-nationalistic. It's China-like behavior (Taiwan, Hong Kong, South China Sea, Tibet).
The EU is getting ready to brain-drain the US.
