Australia is
planning
to permanently exile people that are suspected of somehow
supporting terrorism.
This will start with people who have another citizenship, but the
government already envisions extending it to those who "could apply
for" citizenship in another country. Then it could pay Nauru to grant
citizenship to, and imprison, anyone at Australia's request.
We have come to regard exile as an unacceptable punishment, and we
should not permit it again; but even if we were going to legitimize
exile, we should not accept any form of punishment without trial.
