This would be a monumental step towards committing genocide. If you can strip citizenship for z, y, or z reasons, you can strip citizenship for a, b, or c reasons too. Then, you take those “noncitizens” and put them in a camp. Then you evolve your “solution” to the Jewish Non-citizen Question into a FINAL Solution.
In fact, this could ammount to a crime against humanity under the Rome Statute’s prohibition against certain types of deportation. Specifically, Article 7(1)(d)'s prohibition on deportation is defind in (2)(d), which reads:
Deportation or forcible transfer of population" means forced displacement of the persons concerned by expulsion or other coercive acts from the area in which they are lawfully present, without grounds permitted under international law.
Nazis did this exact thing to the German jews. Admittedly, the United States didn’t ratify the Rome statute, but it did sign it in 2000. I guess the Nazi cancer has been here a while. No time like the present to use a blade.
It’s not that it could be a crime against humanity. Certainly it would be. But when and how to enforce it, those are the questions. The murders down by South America should already get him in locked up in prison, but of course reality doesn’t match international law.
