The EU is getting ready to brain-drain the US.
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.
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).
All of those things can be bought. One of Europe’s strategic disadvantages vis-à-vis America and China is low availability of big, risk-taking cheque writers. Fixing that today is worth more than a working group to write a paper about a holistic solution in ten years.
Thankfully the US is making talent flee, hopefully some of those will wash up in the old world.
