“”You can’t visit Midway anymore, or Iwo Jima or wake””
Why not?
Nobody real lives on the islands. There is no place to stay and no way to get there.
Midway and Wake are bird sanctuaries and it requires a special permit. There is no regular flight or ship that calls at them. Iwo Jima is, from what I understand, a nasty island that is an active volcano. Iwo Jima used to be maintained as an emergency landing place for transpacific airliners in an emergency. I don’t know if it still is.
