USA vs a South American bloc?

Would it be possible for sometime in a time frame between 45-91 that the USA would end up going to war with most of South America or at least one of its major players? I can not find many good articles on American relations with South American countries during the cold war aside from Latin America.
 
US vs. any South American state is a steamroll, US vs the whole of South America is a US victory, with only guerilla warfare really giving the US trouble.
 
The Cold War was arguably the height of US domination over Latin America, regimes even neutral to Washington were few and brief, nevermind directly opposed.

Guatamala in 1953, the Dominican Republic in 1965, Chile in 1973, Nicuragua in the 1980s - if the US isn't directly toppling non-subservient regimes in this period, its at least turning a blind eye to friendly interest groups doing it for them.

Best/only bet would be a NAM influenced bloc (Bolivarian Socialism a few decades early? Peronism goes continental?) forming while a dovish POTUS is around, only for his ultra-hawk successor to try to bring the hammer down and get resistance that escalates.

However unless the said bloc has overt Soviet support (ie nukes for backup), the United States romps to victory in a classic curbstomping exercise. Though jungle warfare wont exactly be enticing. Plenty of domestic CIA funded guerrillas instead I wager.
 
Well, Brazil came close to developing a nuclear arsenal in the 80s:

(From http://en.wikipedia.org/wiki/Brazil_and_weapons_of_mass_destruction#Nuclear_program )

In 1990, President Fernando Collor de Mello symbolically closed the Cachimbo test site, in Pará, and exposed the military’s secret plan to develop a nuclear weapon.[1] Brazil's National Congress opened an investigation into the Parallel Program.[2] Congress members visited numerous facilities, including the Institute of Advanced Studies (IEAv) in São José dos Campos.[2] They also interviewed key players in the nuclear program, such as former President João Figueiredo and retired Army General Danilo Venturini, the former head of the National Security Council under Figueiredo.[2] The congressional investigation exposed secret bank accounts, code-named "Delta", which were managed by the National Nuclear Energy Commission and used for funding the program.[2] The congressional report revealed that the IEAv had designed two atomic bomb devices, one with a yield of twenty to thirty kilotons and a second with a yield of twelve kilotons.[2] The same report revealed that Brazil's military regime secretly exported eight tons of uranium to Iraq in 1981.[2][14]


But that's kinda near the end of the time period.

Your problem's that was there was no big unified grievance for any big, adjacent bloc to unite around after FDR, because that was the end of open US imperialism. Sorry...

There were still rebellions, like Cuba and Nicaragua, but they were notably isolated. Sorry....

Notice that having a nuclear weapons programs' a pretty different thing than wanting to go to war with us. Nuclear weapons programs are usually defensive moves against us, not offensive, but then they can play the MAD card if we look warlike. Iran today has the same thinking, trust me -because if they did use it first, they could count on being nuked to the ground from the sea and losing power.
 
it could be posibble, if all the countries join together agains one common enemy : USa, exc of course for Chile, who is the most capitalist in the continent, ;
even if USa invades south america, it will be imposibble to controll all guerrillas that occur

Okay, WHY?

Well, evil fascist/racist USA (see, Decades of Darkness) but that requires a POD well before 1945.

Hm. US gets into Cuban Missile War, Soviets on Cuba get their missiles launched, US badly damaged enough to go *Fascist, rivalry grows with mostly untouched south America...but we no longer have the cold-war frame for the situation.

You probably need a the 19th century to go better for at least one of the major South American countries in order to create a powerful common market by the 20th century. For instance there is a paradox forums AAR where Chile becomes the world's premier land power and, through physical assimilation of Argentina, common market domination of Brazil and other surrounding states, and education/technology becomes highly attractive to immigrants and foreign capital despite the typical Latin American political turmoil. By the early 1900's, that population and industry is leveraged into developing a fleet to match, and under a short-lived fascist regime Chile successfully defeats a US military attempt to contain their aggression against neighboring countries; though the fleet is sunk/scuttled in the fighting with the superior US fleet.

I don't find the way things played out in the AAR incredibly implausible, it's just not something you can build from scratch; unity between South American countries would take a long time, a long history of OTL rivalry turned into ATL cooperation, to bypass. And that's just one factor, hitting the floor running with the Gilded Age/late industrial revolution is another aspect.

But as a summarizing point, I find it believable that political instability is not an insurmountable factor in establishing these parameters. Extremist regimes come along and temporarily alienate the common market and foreign capital, and are eventually toppled and the relationships are reputations are restored. Honestly, being all the way in South America I think would help a country survive extremist periods, by often being defeated from within rather than without and having restrictions imposed upon it by a conqueror. I think a Great Power could survive coups and restorations better than invasions and foreign restrictions.

So I would start, given this sub-forum's specifications, with the year 1900 and pick a South American country to turn into a Great Power and to build a South American bloc around.
