There are several holocausts going on around the world right now. It's not completely infeasible for there to be another one. I doubt there's been a time in human history where there wasn't at least one holocaust going on.
The German one stands out only because they fought us.
I concur, but only if we sub genocide for holocaust. The two terms are similar, but not interchangeable. I think the distinction is important, but that should not detract from your main point.
You do have a point that Holocaust stands out because we fought Germany, but I would also argue that what makes the Holocaust unique was the speed and efficacy in which it was systematically carried out.
