welcome to the real world mate
Fighting individual countries might favor Russia depending on the country, but I would love to see Putin get his ass handed to him if he dared attack the whole european bloc.
Given how badly Russia is performing in Ukraine, I’d love to see it fail at trying to project power in the EU.
Leaving aside the sheer absurdity of Russia attacking Europe, the fact that Russia has the biggest nuclear arsenal in the world appears to escape you. Of course, you also think that Russia is performing badly in Ukraine, so what else is there to say about you.
