Nope. They should never have been given citizenship. I would check how it was done. (As to me it sounded illegal)
But once granted (if legally done) IMO it needs to have a good reason, court... to be taken away.
I believe there are a few who see thru their leaders. Who would love America. As much, maybe stronger then us native born folks. Because they realize what a amazing country we have. Review how they were made Americans. If as I suspect it didn’t follow the law... give them 30 days to request a meeting to become a American citizen. Then give the rest 30 days to arrange to go elsewhere.
