Europe is not at war. Or at least it wasn't until some politicians decided it was their business to intervene in somebody else's war. This is certainly against their own citizen.
I am an EU citizen myself and I did not consent to join this war.
> Not predicting Russian Imperial dreams of ruling the Europe?
Sorry, but that was never the case and will never be the case.
> Throwing nuclear out the window and becoming so dependent on Russian gas?
Bingo! However, that was not Russia's fault. It was definitely self-sabotage.
