NATO, WAPA and the indefensibility of LandJut in NGP and D85

[JDR Dragoon]

Based on my experience, it's hard for me to imagine that NATO would ever have been surprised by a WP attack.

I don´t think it would have been a surprise either. The question would more likely have at what point in WAPAs decision making process NATO would have become aware that this was "It". Probably more than a days warning, but probably not more than a week either (unless corroborated by solid HUMINT or some kind of code breaking bonanza). You can after all only tell so much from SIGINT (It could foretell that WAPA was up to something "big" in during the Prague spring of 1968, but just exactly what remained unknown untill the soviets actually marched into Czechoslovakia).
