Well, if you want to go there, you might as well go straight to the point and highlight precisely which ideologies you're referring to:
JD Vance, and Elon Musk, supports the far right German anti-european party AfD[0] which has connections to Neo Nazism... You know the guys that are trying to rehabilitate Nazism and Hitler.[1]
JD Vance also expressed his support for a Romanian candidate who illegally took Russian funding for his election run, after a major Russian propaganda campaign in Romania.[2]
So let me clarify your statement:
> Destroying the current European institutions can mean destroying Europe, according to extreme far right nazi rehabilitating parties and Russia.
So yes, according to those ideologies, it can mean that.
