It takes a lot to make Great Britain look like the plucky underdog victim in a sovereignty deciding naval dustup, but somehow Argentina rose to the challenge during the 1982 Falklands War. Oh and a lot of Margaret Thatcher doing that Margaret Thatcher thing.
Recommendations:
Glenn: Arthur (1981 film)
Sarah: The Boat That Rocked (2009 film)
Cameron: Nixon (1995 film)
