The most likely outcome is that the EU is more or less what it is now for the decades to come, and the lack of reform costs significantly in terms of progress, and that Europe misses out on leading key industrial elements and becomes less relevant to global affairs especially as a lot of so-called 'global south' countries become more successful.
The dynamic of Europe sending all the talent to US is probably just going to continue as it is.
Angela Merkel used to be my favourite politician because I thought she was so 'pragmatic' but I think in retrospect she was basically 'do nothing, kick the can down the road, don't rock the boat'.
In some ways, the 'second most dangerous' kind of politician because it's so alluring to even reasonable people.
The kinds of reforms that the EU needs ... which both re-instill a sense of national dynamism but at the same time provide even deeper integration other areas aka capital markets, defence ... almost nobody is talking about.
5 years into a conflict right on the borders, still can't get full sanctions, still buying Russian carbons, still can't get real access to that $100B Russian money, still totally dependent on the US, still have no proper munitions inventory, still don't have proper defence against ballistic missiles aka huge existential gaps in defence capabilities when the wolf is right at the door.
The CIA had to visit Kremlin few days ago to warn against NATO attack is basically admission that Europe, 80 years after WW2 is not fully sovereign. It was daddy DJT that still to this day, is the one at the table, doing the talking. Not Von Der Leyen, not anyone from Europe ... but an American.
The rise of 'ugly nationalism' may cause pro-EU people to rally and defend broken systems instead of reforming. There is a path through that storm that is a wining outcome however...
