This reminds me of stories over the last years(?) of afghan/iraqi translators that worked for the US under the promise of citizenship that got massively delayed at least (with immense risk to their lifes).

In general, the final granting of citizienship in this story seems mostly symbolic, similar to the exoneration of Alan Turing, just that at least some of the ill treated are still alive. It's good it happened and it should be encouraged to make amends for past wrongdoings. But it needs to be accompanied with a change in attitude. Otherwise, it's a hollow gesture, like a child saying sorry after hitting someone, because it learned there won't be consequences like that.

I think that's where peoples onlook on this differ. Is it a symbol of a nation going forward, internalizing the values it claims to build upon - or a mostly meaningless gesture in a system that hasn't really changed and would do it all over again.

Personally (as an outsider perspectice), I feel the US is changing, but the forces are pulling in many directions and it's slow. The current US seems to pay lip service only to human rights but embraces it for propaganda, I hope it works someday and the citiziens will hold its own country accountable to that.
