The US ignores communism in South America

What would happen if the United States ignored the spread of communism in South America? To make this semi plausible, lets say that the communist governments agree to not be allied with the USSR and be neutral in the Cold War. What threat will communist governments pose? Will the people rise up and fight communism themselves, or embrace it? Again, pushing the limits of plausibility, but the government decides that they pose no threat, because they think nothing happens in South America.
 
Different than our history but not by much. The landed and wealthy in South America are powerful and have too much to loose by putting up with communism indefinitely and too many connections in the military. I suspect we'd see communism run economies into the ground similar to what we see in Venezuela in OTL in an attempt to bolster support from the poorer classes. Once it gets bad enough and enough resentment builds up then a military and/or right wing coup deposes them. Strong men and secret police on both sides and the wealthy come out on top no matter who's in power.

So all of America's "help" didn't really change much?

That is IF thry survive the Revolutions. If the Communists gain enough traction and are radical enough... We might see some purges.
 
I have to admit, I'm not that familiar with US anti-communism efforts in SA, other than shenanigans in Chile and Argentina... what else did we do there?
 
Though the US backed and helped coups in Latin America, keep in mind that it wasn't them that executed the coups, but the Latin Americans themselves.

Ignoring the implausibility of the scenario, the wealthy elites are fervently anti-Communist and they knew how to move the masses away from it. Here in Brazil during the Cold War there was a myth that Communists kidnapped little kids to eat them, as absurd as it sounds, many uneducated people believed (like my late Grandmother).

So even if the US ignore the Communist movements, the locals will still counter it (and more likely succeed).
 
It wasn't just communism but any leftist nationalism or reformism. I see a few possibilities:

1. Latin America develops a social democratic consensus earlier.
2. More turmoil as the ruling classes and reactionary forces resist all change-but the leftists get further in more places. Essentially a Latin American equivalent to the Arab Cold War.
