When I think about this, I often come back to thinking that the societies that underwent some conflict or difficult times, absolutely cannot have a member of an older generation in charge, because the only thing they do is to continue that conflict, completely manufacturing it again if needed, just to get their "revenge". Current Russian attempt at genociding Ukrainians is all the more tragic in that the generations, that remember the previous hostilities, were almost all gone by now. Alas, that corner of the world is again poisoned for several generations ahead.
