Not really, it's really different. One shouldn't forget the whole setup of early 20th century. War was a very normal thing, it was after WW I which was really horrible and there wasn't even a UN at the time. National socialism in Germany was about very aggressive expansion combined with very extreme racism, many people were murdered deliberately at all stages of it in an industrialized manner. I would say this remains still very unique. Both humanity and nation states have made a development since then. Certainly one can draw comparisons but there are worlds in between.
