"didn't set out to rid the earth of 'undesirables'." Oh yes, he damn well did. Define undesirables? Anyone, anyone at all, who threatened him in any way whatsoever.

Starting with the usual trilogy, (just like Hitler) gypsies. Jews and homosexuals, expanding to political enemies, army generals, army people generally, intelligence services, bureaucrats, whole states full of people who were being a bit inconvenient, officials, university professors, you name it, he topped them. Or shuffled them off to the the gulags.

Worse, (than Hitler?) or better. Who could possibly say. Except God, and he's being a bit quiet on the subject of tyrants, lately...
