According to this story about Uganda, rape of women is being used as a "weapon of war" and for ethnic cleansing. This, unfortunately, wouldn't be the first time. Cautious estimates say 110,000 women were raped in the Berlin area after world war II (yes, by the good guys). In 1992 between 20,000 and 50,000 were raped in the middle of Europe, in Bosnia-Herzegovian.* Only then the world decided to label rape in war as a "war crime." What was it before that? Boys will be boys? @#$% happens? What?
