I’m kinda reluctant to look to much into 1941-45 for any of this. It was a vastly different war, leadership, domestic context, foreign policy situation, and enemy from what’s going on now. “Tanks in Kursk” is about as far as the similarity goes. Putin isn’t Stalin, as much as he’d like to be, and instead of most of the world’s industrial strength back him up, he has those chuds in NK, some home-brew Iranian drones, and maybe some Chinese cash now and again, strictly on the low.
The Ukrainians have tended to gamble smart so far in this war. They’ve made mistakes, but rarely the same mistake twice. If they’re putting their chips in on this Kursk incursion, I’m willing to believe they know what they’re doing.
