Hawaii is more interesting. I don't think there's a cut and dry solution. There was an internal coup by a mixed race Hawaiian inviting the US to intervene which they did. So obviously the US is in the wrong.

But Hawaii remains an intact state. So the borders haven't changed.

Fascinating history, no clean way to unwind it though.
