Much of this, is not news in many countries, although it lacks solid proof or confessions, it is impossible to keep all that hidden for long.
Brazillians for example figured only one or two years after the US backed coup here, that the coup was US backed. (declassified documents confirmed our suspicions about 5 years ago).
Also, there still many people here waiting to see if documents detailing how our ships got sunk during World War II, the official history is that it was the germans and this is why we joined the war, but WWII veterans swear it was US posing as germans, so they could close the steel mill deal.
When WWII started, Brazil president was very close to Italy leadership, and he was a fascist himself, Brazil was providing lots of resources to Italy and Germany.
Later, US wanted the massive amounts of rubber we had, and of course, wanted Brazil to stop helping the Axis. Then there was the sudden attacks, and a sudden president change of heart, where Brazil would start to supply US instead, specially Jeep tyres, would buy a steel mill, and would help in the African front lines... this got changed to Italy mid-trip, with Brazillian ships dumping into Italy snowy mountains people trained and geared for a desert war...
I know a bunch of people (specially, obviously, fascists, but many non-fascists too, but most of them are over 50) that still resent that story, and wish Brazil had joined (with boots on the ground) the Axis side instead.
Also Brazillian soldiers got shafted hard by the US, specially the "rubber soldiers". US and Brazil made a agreement, where drafted people could choose to fight in Europe, or get shipped to Amazon (with several promises regarding the advantage of going to Amazon, and indeed 50.000 soldiers went to Amazon), they would gather the rubber to make tyres, and US and Brazillian government would jointly pay them and take care of them, and return them back to their family after the war... The payment arrived (and partially) only in 1988, and they are still stranded away from home... (some of them still roam the forest wearing their military uniforms, kinda creepy seeing 90+ year old soldiers roaming the forest)
