I think you misattribute, everything you cited was there before him and he had no leverage to change any of it. EU is left, FR is very left, and anyone elected president in FR can't do shit.
Now, if you task an LLM to skim hot news you'll get a distorted rendition of a projected image which has zero to do with actual policy.
You are out of touch. The left supports the EU far more than the right. See this Pew poll from 2025[1].
In Europe, for every country, the left view the EU more favorably. The largest difference is in Poland where 88% of left wingers support it and 41% of right wingers support it.

Hitler and Mussolini haven't got up there by themselves, they were symbols that personified current beliefs.
It is the same with Putin for example: he rides some (diminishing, but still there) amount of faith. Absent that he would have been silently buried long ago.
