So know one was buying the Argentinian claim that they were just liberating the islands from European imperialism?
I got to know some Argintinian girls when I was in Grad School. They thoroughly believed that the Falklands are theirs and that the British took them by force from Argentina over a century ago. The invasion was simply reclaiming their historic territory. This propaganda is still the standard inn that country.
Predictably, the "Daily Worker" American Communist Party crowd were taking that line. I remember arguing with some guy trying to sell the rag on the street over it. But that was mostly reflexive anti-American/anti-Reagan/anti-Thatcher sentiment rather than a seriously thought out position.
