People there, from young age live with constant repetition of same soviet style messaging: “west is conniving and bad (and don’t forget - rotten); we won WW2; USSR was best in the world at X, Y, Z; Kiev Rus Vikings; inheritors of eastern Rome something…”.

Those messages are indistinguishable part of national (almost personal) pride, even for a lot of russian speaking people that currently live outside of Russia.
