All the countries there succumbed to Leftist / Populist takeovers, with all of the attendant nonsense. Several countries there have been through cycles of left-to-right-then-back-to-left.
What was different in Chile was the coup that brought Gen. Salvador Allende to power and his methods of dealing with the left.
The military dictatorship in Chile lasted from 1973 to 1990. The leftist Salvador Allende was overthrown in a coup, many claimed the CIA helped engineer. Allende was a communist and aligned with the Soviet Union, and the CIA still took a dim view of such people leading nations in our hemisphere, in particular, in 1973.
Here's a bit about what was done:
Two years after its ascension it implemented radical neoliberal economic reforms in sharp contrast to Allende's leftist policies, advised by a team of free-market economists educated in American universities known as the Chicago Boys. Later, in 1980, the regime replaced the Constitution of 1925 with a new one crafted by regime collaborators. Pinochet's plans to remain in power were thwarted in 1988 when the regime admitted defeat in a referendum that opened the way for democracy to be reestablished in 1990. However, the regime took great care to ensure that the political and economic system it had created would remain unmodified.[3] The regime also arranged for the military to be out of civilian control after the end of dictatorship.[3]
And of course to accomplish that the Left were put down, with little concern for human rights. Approximately 3,000 Leftists were summarily executed, often by being kidnapped at night and thrown out of helicopters 10 miles offshore after their torture and interrogation by the security forces.
Following their takeover of power in 1973, the Government Junta formally banned the socialist, Marxist and other leftist parties that had constituted former President Allende's Popular Unity coalition.[12] On September 13, the junta dissolved the Congress and outlawed or suspended all political activities in addition to suspending the 1925 constitution. All political activity was declared "in recess". Eduardo Frei, Allende's predecessor as president, initially supported the coup along with his Christian Democratic colleagues.As a result of killing three thousand, and arresting and interrogating another 200,000 "self-exiled" by leaving Chile. This in a country with a population of 10 million at the time.
This is what it took to delouse the nation of Chile. A generation of military rule, an uncompromising commitment to ridding the nation of leftists.
If we scaled the operation up for modern day America you are talking about on the order of 7 million people being forced into exile from the USA.
Efforts to cleanse South America of the vile leftist infection that have been attempted using less extreme means have all pretty much failed.
I’ve been to Chile and it’s a model nation in South America. Pinochet was justified in his actions! It’s also nice visiting Argentina even though they’re having some economic problems but that means our dollar goes far down there.
It’s called solving the problem once and for all, and it’s the only way that works.
