Sent aircraft carriers, ships and soldiers to help depose a democratically elected president, just because he wanted closer ties with China and wanted to do agrarian reform.

Disappeared lots of people (I don't know any personally, because I am too young, but I DO know personally lots of people that still want disappeared people back)

Spied on us (erm, that part still applies, no?).

Sabotaged our agriculture (ie: some plagues started after US agrarian engineers visited us to "help" with our agricultural technology).

Supported and funded very repressive crazy dictators that killed boatloads of people.

What the USSR did for us during the cold war: Gave us some really cool technical books in spanish (yes, our language is portuguese, but spanish is good enough), I still have a bunch of them, they are really good, somewhere around my house there is calculus books, structural engineering, and lots of other cool stuff, russian books but written in spanish, targeted at Latin America.

USSR borrowed us some scientists (Russia and Ucraine still do, by the way).

Helped our exiles, not only left wing ones, but right wing ones too.

Sold us some very interesting stuff, even if shitty sometimes (example: during the cold war Lada cars were very popular here).

Computers! (for example when some companies here tried to develop a computer compatible with the Macintosh, US government helped Apple in forcing them to stop, while Russians borrowed us some engineers and books)

Now, who were our real enemies in cold war again?
