The government is claiming that their decisions are not reviewable by the courts. If the courts accept that argument, then tomorrow the President could proclaim that we are being invaded by, say, the Yakuza, and send any non-citizen Japanese person to a prison in El Salvador and the courts would have no power to question them.
There is nothing stopping the President from using this enormous, unchecked power against his political opponents.

Why would he do that? Manzanar is much closer and successfully tested even against citizens.
I’ve heard that interned Japanese-American did not like to bring the whole thing up afterwards, but it was clearly a mistake trying to memory hole that abomination.
So your argument is a slippery slope argument. The government can do a lot of things. But it doesn’t. This action against violent criminals seems like an obviously good use of the law. I’ll worry about your theoretical slippery slope if and when it becomes an issue.
Also, what do you mean by “political opponents”? Are non citizen Tren de Agua members voting or running for office? If not, how are they political opponents?
The US government is currently doing crazier and crazier things on a daily basis, and is run by a guy who’s pretty much open in saying that, actually, he likes doing crazy things; the courts and legislature have made barely any attempt to stop this. I mean, at this point, I don’t think the slippery slope fallacy really applies; the crazy guy who’s obsessed with vengeance against perceived enemies may well get it. Do not assume that there is a limit.
The President has threatened to deport many people because of their political views, and he has already arrested at least two that I know of, plus one more who left the country before she could be deported. So it's not a "theoretical slippery slope" argument.
It's already likely that some people were shipped to Guantanamo who were not criminals[1][2]. They were kept in horrible conditions without media access and left without legal recourse or any means of communication with the outside world. Is that OK with you? What happens when Trump decides that "Democrats" or "leftists" are the enemy now, as he's been continuously suggesting[2]?
