A really left-wing government in Argentina is very unlikely, not only because the military wouldn't tolerate it, but because the kind of people who might support far-left parties elsewhere in Latin America were Peronists in Argentina.
One thing that I'm curious about is how the US would conduct similar scale operation as the UK did. Of course it's not realistic, but if the US did for some reason decide to do it on a shoe-string what would they send? And how would it do?
there was concern over them, but the temptation to take down a shiny new Soviet client was pretty overwhelming... the US troops didn't get to the students for a looong time after the invasion started...I had always thought that the students held hostage combined with the instability was the real reason.
