HP is right on western vs eastern europeans - in culture, attitudes and everything.
Hell, they even differ in looks, if someone europeans walks in the streets of beirut, we can instantly tell if he/she's western european or eastern european.
We can't tell one is whether German or English (They look alike, both Western) for example without asking the person, but we can easily tell whether he's western, not eastern looking.
US / UK / English part of Canada/ Aus / NZ are all one same Mega civilization ,which itself is the biggest portion of the West.
