Re: Breaks it angle
Yup, matches what I've read about things - the State Department wanted to back Argentina as a key ally in the war against Communism (never mind the yearly state-sponsored murders), and didn't care about the UK, because we weren't going to abandon NATO/Democracy, etc. The US military wanted to back the UK, as a (broadly) trustworthy / key military ally (that had the added advantage of being in the right), rather than a dictatorship that murdered several thousand of it's own people each year.
