Ok, just a small step back to one of the books about colonial wars I posted on some time ago. I follow the excellent podcast series New Books in Military History, which has an interesting selection of new material. Some time ago I listened to a comparison of genocide and conquest on the Eastern Front in WWII and the the American West.
What I found interesting is that the author, Westermann, took up this project based on discussions in his classes, where he found the students would naturally compare different forms of genocide. When it comes to genocide, Nazi Germany remains the archetype/Idealtype, although the last decades our historical knowledge of other genocides has widened.
Of course looking at genocide involves a discussion of the definition, but most definitions go farther than just the mass murder of a particular group with the intent of total destruction. Some include the destruction of culture and separate identity.
While it easy to dismiss referring to the Holocaust as a Godwin, in this vase it is actually helpful.
Westermann notes that what happens 'at the sharp end' of policy doesn't necessarily align with what happens at the centre. And while what happens at the sharp end may seem very similar in both cases, Westermann argues that the main difference between the American and the German case is that in the former, the authorities were not bent on genocide and in the latter they were.
It's worth listening to his argument in full.
