The idea wasn't to destroy Europe, just the bit with the soviet tanks and supply lines on it... And the Germans were more gung-ho about it than the Americans. https://translate.google.com/t... is a terrible automated translation, but if you know german maybe you can read the original, the whole thing is crazy, but in particular:
German Defence thought meet NATO with a conjuring trick. He wanted to make up for the shortage of soldiers with an atomic micro ordnance, with the atomic mortars Davy Crockett.
Strauss also not allowed to be disturbed by reports of his officers from Washington. In the American Army General Staff had, laconically replied to the question of whether Davy Crockett could replace conventional artillery: "No way!"
It was a scary time - I'll take today's crazy terrorists over it actually. NATO truly believed that they could not repel a soviet invasion with conventional forces, short range nukes (heck nuclear mortars even) were honest to goodness plans... Of course Putin is doing his best to revive those old days.
A Trump v Putin game of chicken does not sound like a wonderful thing, I must admit...
