Was that the only real estate available? Really? Other cultures got fucked, and worse, and they didn't even get a shitty consolation territory. Is it the displacement thing? The Dacians got brutalized by the Romans and their tongue became a Slavic Romance language as a thank you. And most of the Celts and Gaels, they got fucked twice, first by Rome then by... whatever you call the Anglo-Saxon-Norman conglomerate that put the cultural screws to Scots, Irish, Welsh, Cornish, with the French adding a little of the old ultraviolence onto the Bretons. And then the Reconquista. The only reason it wasn't a bloodbath of a larger scale was a smaller population and no death machines.
Also, did we ever force Leopold to eat a bullet while we burned his capital to the ground? If not, we failed as a species.
