I found it creepy, too. But I also have a habitual interest in the cold war and weapons are where I first encountered the fascinating world of technical specifications. It was something I shared as a child with my father - who was a small boy during the Second World War and a research scientist for the USDOD his entire professional career. That doesn't make me a fan of killing or war. It just means that I have contradictory interests. So obviously I read the article and enjoyed it.
I also puzzled over my enjoyment. The human toll at Stalingrad [celebrated by the author] was immense, and as I have aged I have lost the convenience of demonizing other people through stereo-types. There but for the grace of god, go I - without any belief in the concept of god which it might suggest.
So I appreciate the writing and struggle to find a place for the enjoyment I gained from reading and still mull over what it ignores and celebrates. That's what makes it good - it has a take and doesn't suck.
