I admit I've become rather fond of Walt. We clearly have various disagreements on what's likely to happen in Ukraine, but he is willing to acknowledge that things might turn out the way you and I think they will.
There was a war that never happened. It was the WWIII where the USSR swept over the northern plains of Germany. Everyone spent a half century planning for that war. Almost all our weapons systems were made for that war. It was a constant part of our lives, and never happened.
In JROTC, I also planned for that war. I was not even an amateur, but I was at the beginning of training. And the war that never happened was what everyone was training to plan.
The plains of northern Germany extend into Poland, and then down into Ukraine. Even though Ukraine is further south than northern Germany, it is also further inland which evens things out. It is almost the same temperature, and climate as northern Germany. Ukraine is not getting as many NATO weapons as NATO would have had in Germany, and Russia is not as strong as the USSR used to be, but there are definite similarities in the weapons on both sides.
I do not like that this war exists, but it is answering some of the questions about the war that never happened. We are finally testing all these weapons systems, and strategies in a similar war. It is just fascinating.
