God's Comfort Women

I read today that a Japanese politician has declared it was "necessary" during World War II to force 200,000 or so women to become sex slaves for soldiers as so-called "comfort women". My first thought was, "Well, that's pretty much what God commanded in the Bible in Numbers 31", except that in God's case he also commanded everyone captured who was not going to become a sex slave be killed. God only wanted the virgins kept as war booty (no pun intended), and got sort of irritated when the other women weren't immediately slaughtered. This wasn't the first the first or last time God advocated (I mean "commanded", of course) genocide and other war crimes. Maybe former Guatemalan dictator Efrain Rios Montt, who was just found guilty of genocide, should just say that God told him to do it.
