Doesn’t seem much different from the scenario by Sir John Hackett in 1979.
How reliable would Warsaw Pact countries be? The Poles wanted to throw the Russians out. And the Chezchs still remember Prauge Spring.
An old saying” Better a known enemy than a forced Ally”. The Warsaw Pact was for the most part a forced ally. They would have fought,but as hard as Russian troops.
Needless to say we are all glad this didnt happen.
In a college simulation, my country was invaded in a sneak attack and I nuked the invader’s country to oblivion with a first and second strike before they even got anywhere.
There was nothing left.
Hope it taught them a lesson.
BTW, in this scenario, nuclear weapons would likely have been used on 2nd echelon Warsaw Pact forces in Poland long before any Warsaw Pact breakout in the Fulda Gap (where I would have been fighting).
Just my humble opinion of course.
