The only offensive thing here is that the trailer features a Panzer IV with sideskirts in North Africa.
Nice catch.
For earlier in the thread there have been plenty of german campaigns, and every one I've played had little to no reference to nazis or their emblems, focusing purely on military matters.
Panzer General was the first and it was done pretty well. Panzer Korps has a dedicated desert campaign and was very much a modern version of Panzer General. The german campaign in Hearts of Iron 2 somehow managed to inject political stuff (annexation of austria and sudetenland among a long list) without nazis as well.
