Well if ya think about it most of the modern era has consisted of western civilization versus an enemy which has generally consisted of eastern Europe. So of course in popular culture as well a distinct enemy is going to be defined as well. Starting to already see a shift towards "terrorists" too in some games as that becomes more popular with American developers.
I don't think it is necessarily hate but the people who are creating games right now are ones that lived during the Cold War so these notions of an "enemy" are still going to somewhat persist.
