This horrifying link shows Japanese and American war crimes and torture of the innocent Chinese citizens in Manchuria China.  It graphically shows inhuman medical experiments conducted on tens of thousands of human beings.  At first it was just the Japanese doing it,but after WWII US General Doublas McArthur, one of the most decorated men in U.S. history, a five star general, covered up these war crimes and sponsored and paid for the Japanese doctors to continue their hideous human experiments so he might send the Bubonic plague to Korea.  See the link and you will have a different perspective of just how cruel America could be.

     But it also shows why Japan had to be stopped with the atomic blasts.  If they were not, the Japanese would have infected the US with the Bubonic Plague just 2 weeks later.  It puts things into perspective.
