An important point. I make no distinction between Hitler and Stalin, as embodiments of absolute evil. Likewise -- I think, having not read much about it -- the architects of Armenian genocide.
Dresden and Hiroshima are in a separate category, for reasons that IMO are so obvious they don't need to be spelled out. Someone more patient or less lazy than me can have a go at it.
Supposedly Hitler said he would 'get away' with (then assuming he would not lose WWII) the holocaust because the Turks 'got away' with killing the Armenians.
"Obvious"? You mean that they were as evil as those other massacres? I am not sure what you mean?
