Diligent, Are you joking? Stalin was a US ally in WW2. Mao, didnt murder as many Chinese as the Japanese did.
Pol Pot? Now, that is a disgrace. The US abandoned Cambodia with helicopter extractions from the Embassy rooftop a la Saigon....leaving their staff to be butchered by the Khmer Rouge.... and thus allowed the bloodbath that followed.
Robert Mugabe? Strewth, Dili, the person directly responsible for Mubabe numero uno, was our Prime Minister Malcolm Fraser. He pushed for Mugabe against another candidate. Also, Fraser made it illegal for Australians to go and fight for Smith against Mugabe and his TERRORISTS. Yeah, thats what they were, slaughtering nuns and social workers. You really havent a clue, mate. Hey? If Fraser hadnt done that, Zimbabwe might be different. I never got there, near the end, but a mate who did, an armourer with the RAAF, who fought with the legendary Selous Scouts, had problems on returning to Australia....they gave him a hard time...and he was born here. You still cant see anything unfair, eh? You never flaming will. Just carry on painting white spots on the ceiling, Dili, as people die due to the attitude of clowns like yourself.
