Hundreds of thousands of people from other countries were tortured, raped, or killed.  People were often killed by mustard gas bombs.  More than 1.5 million German women were raped from the Soviet Union.  Recent evidence shows that Stalin had his own Final Solution in which hundreds of thousands of Jews were exiled or killed.  Stalin wanted the Soviet Union to become a country strong enough to rival the U.S., but if they were stronger than the U.S., he would want the 2 countries to fight a war.  Stalin killed 20 to 60 million people. Stalin ruled over Russia from 1922 until his death in 1953.

From the outset, Hitler blamed Germany’s problems on those with impure blood.

Hitler’s master plan was to create a German Reich of genetic purity. This, of course, put into motion the events that culminated in World War II and the murder of six million Jews as well as thousands of social outcasts like homosexuals and the handicapped. Facing defeat, the ever-malicious Hitler convinced his wife as well as close aides and their family members to kill themselves.
