Well, let me put it to you as gently as possible...if the Romans had conquered your ancestors all the way to the Baltic and the Danube the Germanic tribes would have become civilized a lot sooner and maybe avoided a whole lot of unpleasantness over the ensuing centuries...just saying !!
Europe is still divided between the Germans and the Romans.
If civilisation by conquest is such a dandy idea, then where is the Roman Empire today?
