As long as we are sucking oil out of those deserts and gun money out of oil Sheiks, the US will have a presence on Diego Garcia. It’s the only reliable American-‘owned’ piece of land in that whole hemisphere. The next best was the Philippines, but they had enough people to maintain occupation of theirs and get paid until a volcano destroyed enough of the US’ sunk costs to make leaving look good on a spreadsheet.
It’s a damn shame that the Chagossians got screwed by white folks. They should be paid as much as Britain is/was. Eventually, Russia will pay them with submarines and drones if they aren’t. Sure, some people get fired up over legacy land and origins (and SAY they don’t care about the money), but that’s just religion. New religions are started every day now (and they’re all wrong).
From a pragmatic standpoint, they should work to get something tangible (besides folk songs) out of it before it’s under water instead of letting philosophy get in the way of their children’s lives.
Maybe they can get the Mafia to help them put a casino on it so their kids will have jobs. That’s what my high school did.
