From the late 80's, call it 1988, NATO would have won hands down. a toss up in the mid 80's and a WP win in the early 80's imo. I worried most about air cover and heavy artillery. if it would hit us and not the enemy,How long our big guns would last, if we'd have any air support, ect I never did trust the Airforce
. Nukes would have sure changed things to the point of no one winning at any point imo
