The Khmer Rouge is an interesting example, as it was a left-wing totalitarian government that the USA supported[0], albeit often at arms length. It was part of the geopolitics at the time, as the USA was aligned with the PRC and the Khmer Rouge against the Soviet bloc. A lot of it was also a petty vendetta against Vietnam, as arming the Khmer Rouge was a way to get back at Vietnamese Communists for winning the Vietnam War.
From the Wikipedia article on the Pinochet regime [1]:
> The regime was characterized by the systematic suppression of political parties and the persecution of dissidents to an extent unprecedented in the history of Chile. Overall, the regime left over 3,000 dead or missing, tortured tens of thousands of prisoners, and drove an estimated 200,000 Chileans into exile.
From the Wikipedia article on Carlos Castillo Armas [2]:
> Upon taking power Castillo Armas, worried that he lacked popular support, attempted to eliminate all opposition. He quickly arrested many thousands of opposition leaders, branding them communists. Detention camps were built to hold the prisoners when the jails exceeded their capacity. Historians have estimated that more than 3,000 people were arrested following the coup, and that approximately 1,000 agricultural workers were killed by Castillo Armas's troops in the province of Tiquisate. Acting on the advice of Dulles, Castillo Armas also detained a number of citizens trying to flee the country. He also created a National Committee of Defense Against Communism (CDNCC), with sweeping powers of arrest, detention, and deportation. Over the next few years, the committee investigated nearly 70,000 people. Many were imprisoned, executed, or "disappeared", frequently without trial.
"Totalitarian regimes are different from other authoritarian ones. The latter denotes a state in which the single power holder – an individual "dictator", a committee or a junta or an otherwise small group of political elite – monopolizes political power. "[The] authoritarian state [...] is only concerned with political power and as long as that is not contested it gives society a certain degree of liberty".[8] Authoritarianism "does not attempt to change the world and human nature".[8] In contrast, a totalitarian regime attempts to control virtually all aspects of the social life, including the economy, education, art, science, private life and morals of citizens."
So Chile and Guatemala were Authoritarian, but not Totalitarian. The practical difference is that an Authoritarian Chilean government kills 3,000 people while the Totalitarian Khmer Rouge kills 1.5 to 2 million of its own people.
"Perhaps from 710,000 to slightly over 3,500,000 people have been murdered, with a mid-estimate of almost 1,600,000. But these figures are little more than educated guesses"
Saying they are the same thing is ridiculous and really soft pedals how insane some communist regimes were.
There is no defense of the Pinochet era. I believe that his predecessor tragically abused governance though, seizing control over so many lives, there and abroad.
I feel this is such important context for what followed. It raised such a fervor of hatred toward the communist political body. I still believe this was theft of property from people's families and estates built over many generations of effort.
