That is true sometimes but Stalin, Mao, and Ho Chi Minh all died of basically old age or normal causes.
Bill and Hillary Clinton are both celebrated figures whose long list of criminal or unethical conduct seems to have been forgotten.
What I am saying is that history will not judge them well. We may not live to see it. Stalin, Mao et all are loved by who? Degenerate communists and leftists. Chi is the same way. IE, people just like them. But the books still tll us of the hundreds of millions they killed. That is their legacy. They are hero only to criminals, communists and the insane.
Their ‘teachings’ are rejected by any decent people. And decent people eventually win out EVERY time.
Imagine in 500 years, when there are (assuming humanity still exists) no Axelrods or Carnys with a vested interest into propagating the myth of Obama/Clinton. No one getting paid to lie for 500 year dead people. Sure there will be the equivalent of today’s sycophants. But they will be living in a world destroyed by those people...the aftermath of it.
Short of utter nuclear annihilation that blasts life to the cellular level, there will exist many records and physical reminders of today, just as we have relics from the Egyptians we have deduced their history from. I do not believe some future humans will be so invested in pretending our history was something other than it is.
