Dowding, come down off your highly-evolved holier-than-thou crumpet-munching pedestal for a bit. The person I presume your UID refers to used what 'could' be described as mass murder of women and children in their beds, they too were innocent in that their only crime was being in the wrong country duing a war. But killing a few million civilians in a short period of time did a great deal to bring the agressive country to its knees.
After the Greeks and the Romans, the Spanish defeated the Moors, I guess those kind of defeats only last a few hundred years or so.
