It's absolutely comparable.
Comparable - being able to compare.
Germany had concentration camps for (primarily) Jews. Which, started out as land appropriation (amongst other things). Which, as most of us know, later developed to much more inhumane methods of handling their citizens.
USA, after Pearl Harbor, implemented Order 66, in this we created concentration camps for Japanese Americans on the basis of Japanese Ancestry - not nationality - per the text listed above. It was a racist order that didn't take into consideration other races who lived in Japan before that time. Just the Japanese people.
Kinda like Trump's Muslim Travel Ban.
