In the sense that the government had the logistical capacity and capability to do something like this, yes.

Culturally I don’t see it as somehow exceptional. US government regularly employed highly authoritarian policies to suppress or remove people based on racial or ideological grounds since the very beginning.

Even in WW1 German Americans had the benefit of being white and forming a very significant proportion of the population so anything like this was obviously infeasible. But their cultural and linguistic identity was suppressed and they were forced to assimilate under the threat of violence.

When you take the Sedition Act and other similar policies in relation to how much of a threat US faced in WW1 compared to WW2 I’d day what Roosevelt did wasn’t that extreme.

I agree repression has always existed in the U.S, but the difference is scale.

In WWI the country was smaller, less centralized, and suppression was cruder - local violence, language bans, mobs.

By WWII the U.S. was far larger, more cohesive, and had a strong federal state; without that scale and central capacity, something like internment would have been much harder to pull off.
