Bolivia is suing Chile at the International Court of Justice, seeking to overturn the results of the War of the Pacific (1879-1883), and regain access to the Pacific Ocean (most of northern Chile belonged to Bolivia before the war).
Most commentary I have read says, not surprisingly, that Bolivia doesn't have much chance of winning. I suspect that there's even less chance that Chile would pay any attention to such a ruling.
But, on the off-chance that the ICJ rules for Bolivia, I wonder what the next such case might be: Perhaps the Romans could be ordered to pay reparations to Carthage?
PS: I wrote almost a year ago about the practice of countries (Bolivia was one example) using old grudges and other nationalistic tricks to distract their populace.
