Especially given that recent history has shown us that we're back to "power" being the only language spoken.

Rel: The ecosystem thing.
I would challenge that, because if there's one thing where the US has had absurd leverage over the EU (and world, for that matter), then it's tech ecosystems.
A healthy ecosystem would not be owned by SV/US alone.
So right now, we're not really "strong together" but rather weakly dependent. That should be remediated, and decoupling like this is exactly the tool for that.
"Power being the only language spoken", never left in the first place in order to get back to it, it's how the world always worked and will always work.
Granted, power wasn't actually the "language spoken", but more accurately it was the stick ensuring the enforcement of the terms agreed within the "language spoken", a lesson as old as time that many in EU forgot after post-USSR collapse and now have to re-learn it, but at a heavy cost and with added interest.
"Those who forget history are doomed to repeat it", couldn't be more true.
That's pretty damn obvious to everyone with a half of brain, yet here we are being pulled apart.
There is a very credible argument to be made that excessive cooperation leads to incredibly heavy overly political programs that are completely static and can't adjust because of international agreements.
That doesn't mean working together isn't good but they way they have been has been pretty questionably in many ways (along with a lot of space policy).
