WWII: "When millions of men were slaughtering one another to decide what colour the concentration camps of the future were going to be—brown or red."

  

"I was born [in the Soviet Union] at the very height of [World War II] when millions of men were slaughtering one another to decide what colour the concentration camps of the future were going to be—brown or red." 

~ Vladimir Bukovsky, from his memoir To Build a Castle: My Life as a Dissenter
