Why does Russia not like the western world

pureblossom i will try to put this in a nut shell if i can it stems back to the russian revolution and the rise of the communist regime after the end of the second world war europe became split between the pro communist east and western society and germany was divided between the communist east the soviet bloc an the pro west a cold war developed and the east bloc led by russia military build up began on both sides and of course the building of the berlin wall splitting east and west and suspicion and mistrust leading to stand off between america and russia when the soviet block crumbled in the late eighties and gorbochov more acceptance there was a time where there was more cordial trust between russia and the west but change of presidents in the united states they have become a little frayed and the suspicion and mistrust has reared its ugly head again
