I've read a lot about it actually. I wonder if maybe you haven't read a lot about what the US has done to its prisoners.

Also are you really saying unit 731 was worse than killing 4 million vietnamese, or helping pol pot kill a quarter of his country, or killing 20 percent of all Koreans and installing a military puppet in the south? Or using sanctions to cause mass starvation of an entire country that we've spent twenty years occupying or destroying?
