A brief (and by no means complete) rundown of Henry Kissinger’s crimes against humanity:
He sabotaged Vietnamese peace talks
He bombed the shit out of Cambodia and Laos, which led to the rise of Pol Pot and the Khmer Rouge
He helped overthrow a democratically-elected president and put murderous dictator Augusto Pinochet in charge of Chile; Pinochet murdered tens of thousands of people
He tried to stop Carter’s government from ending mass-murder in Argentina
He supported Indonesia’s invasion of East Timor, which led to the deaths of about a quarter of East Timor’s people
In short, he’s spent his whole political career supporting mass-murder and oppression, and the United States has rewarded him for it over and over again.
