It doesn't matter if they're citizens or not if the government is skipping court thus not being required to prove it either way. Then when they oopsie you to another country they have to at least try to pretend to get you back but the courts need to show "deference owed to the executive branch in the conduct of foreign affairs".
Which is a long way of saying the executive can blackhole anyone it wants to a foreign country and no one is going to do anything because god forbid we step on the executive's role to give up people in our country to other countries.
