> The previous time the alien enemies act was exercised (putting Japanese Americans in camps during WW2) is widely viewed as having been highly inappropriate and regrettable act.

This is often incorrectly cited as the last time the Alien Enemies Act was invoked, but EO 9066, under which the exclusion, and subsequent forced relocation of, Americans of Japanese descent from large swathes of the country, and some others, occurred does not cite as authority and was not tied to the Alien Enemies Act (which, by its own terms, only applies to aliens, not citizens.)

There were invocations of the Alien Enemies Act in the earlier proclamations of Dec. 7 and Dec. 8, 1941, but the exclusions and forced relocation under military authority under EO 9066 was broader and not based on the Alien Enemies Act.

I get that EO 9066 wasn’t directly tied to the Alien Enemies Act, but the internment itself still relied on wartime powers and ended up targeting Japanese Americans unjustly. Do you think the legal specifics change how we view the regret over those camps today?

Also FWIW Reagan's apology was addressed both to citizen and non-citizen victims of the camps.

I think whether or not, and how, it was tied to the Alien Enemies Act is more than a little relevant to considering what purpose it can serve in discussing the Alien Enemies Act.

How we view the regret over the camps is, outside of that, mostly irrelevant to the context in which the issue was raised in this discussion.

How do you arrive at that conclusion?

The Japanese internment camps held both citizens and non-citizens. The camp in El Salvador currently holds mostly non-citizens but Trump issued a statement where he expressed enthusiasm for putting "home growns" in the camp as well. It is speculated that "home growns" refers to US citizens.

Obviously EO 9066 was necessary because the alien enemies act wasn't sufficient to intern citizens, and both citizens and non-citizens were put in the camps. Trump's comment about "home growns" suggests that he may issue a similar order, which in my view makes the two situations quite analogous with respect to the principles of law involved in taking people into custody without trial.
