They are still smart.

Look how Germany flourishes despite the fact their country was in ashes, most of their productive male population and industry gone after WWII.

Not to mention public opinion against them which to some point lingers on today.

I have respect for the Germans and how they rebuilt Germany.

They should be proud now for what they have accomplished after WWII and stop feeling guilty about the sins of their grandfathers which they had nothing to do with.
