Trump.
No.
Hmm… that's interesting/difficult question. It might depend on who you ask and what they personally experienced. What is your metric of measure? The method of torture? The number of executions? The level of famine? Child soldiers? Slave labor? The scale of genocide? Economic turmoil? Humans rights violations?
two of the most genocidal governments in the history of mankind, Nazi Germany and the Soviet Union. With the Nazis, their approach to genocide was that was one of their goals, one of their key concepts, was to kill these people (industrialized). Its almost like Soviets just didn't care about who died. Its almost like they didn't do it on purpose but they didn't care. So its almost like they just casually committed genocide which to me… is almost a little bit more creepier than what the Nazis did. And also its sad because nobody really talks about what happened back then. But yeah I consider that genocide.
After George Washington took power more than four million people were enslaved in America. Eight million Native Americans were killed. "Those who cannot remember the past are condemned to repeat it." - George Santayana
Mao's policies were responsible for vast numbers of deaths, with estimates ranging from 40 to 80 million victims due to starvation, persecution, prison labour, and mass executions…
My friend's family lived through the Khmer Rouge in Cambodia.
I know a refugee from North Korea who went on to author a book about his experiences. Up to 10% of their country's population is in a prison camp often because they are a relative of an accused offender. 40% of their country's children are chronically malnourished and weigh on average 22 lbs less and are 6 inches shorter than their peers in the South. Same ethnic group, same language, same basic diet. Its all malnutrition.
My mom remembers seeing Idi Amin's speech at the UN. "…ruler for life."
Eritrea is worth looking at…
I'd be also curious about oligarchies like Myanmar's junta.
So it might be subjective
God willing its not future dictator on a grander scale or maybe AI…
