In the early 1980s, Argentina was in the midst of serious economic problems. The country's ruling military junta decided to invade the Falkland islands as a way to distract public attention and to get the populace behind the government. The whole idea flopped when Britain surprised the junta by resisting.
Argentina gets itself into financial trouble with distressing regularity, and each time the government seems to react by making nasty noises about the Falklands. I posted this two years ago when they were doing it, and brought up a couple of other examples.
