Definitely far from my expertise but I think you're contradicting yourself.

I am talking about the formalization that is specifically the modern European Union. You are talking as if it's some inevitable consequence of earlier efforts.

> Europeans who created the EU knew about balance of power geopolitics so well, they created this slow bureaucratic mess specifically to stop Germany and France sliding back into the same old lethal habit.

I don't think anything you're saying is strengthening this statement that I had an issue with.

The Maastricht Treaty which is what created modern day EU was driven by other concerns, asking Gemini yields: "To answer your second question: No, everyday Europeans in 1992 were not primarily thinking about WWII.

By the time the Maastricht Treaty was being drafted, the public was reacting to a completely different era of history. They were focused on the collapse of the Soviet Union, the opening of Eastern Europe, and the need to compete economically with the United States and Japan in a rapidly globalizing world. The defining event on the public's mind was the Fall of the Berlin Wall in 1989, not the end of WWII."

So you are right that the processes that eventually led to the formation of the EU started after WW-II due to concerns related to that war. But specifically the EU as it stands today with its current structure and agreements was not formed due to those considerations. Europe could have continued with the previous arrangements. At least that's my take and I don't think anything you're saying contradicts it. I'll admit to a certain lack of knowledge so happy to learn more about Europe pre-EU or why what I'm saying is still wrong.

EDIT: I guess one can see how the reunification of Germany was a factor that could have made people consider the world wars. That said the creation of the EU was a major change compared to previous arrangements.

EDIT2: When I read the EU site you linked to I get a strong sense of "backsplaining" as if it was written after the fact to appear like the EU was just part of a process that goes back to WW-II. The title says "History of the EU – 1945-59" but in 1945-1959 there was no EU. Didn't the term European Union only show up circa 1992? So this is perhaps the "history of Europe" but not the history of the European Union? I could be totally wrong. I am not European but I did live through these events and follow the news (well, not WW-II but the fall of the USSR, Germany's unification, and the establishment of the modern day EU). What's of interest to me in the context of this specific question/debate is what were the concerns of the Europeans and their leaders entering into the agreements that formed the modern day EU.
