TBF any NATO vs Warsaw Pact war past the mid 1950's was going to end up like That Scene From War Games and everyone knew it.But, but muh Fulda Gap.
Funny fact, for all the waxing of American planners about Fulda gap, Soviets never planned their main strike there but fuhrter North, through NORTHAG area, Fulda gap would only see supporting attacks, to pin Americans in place.
The main offensive worth of Iran was the capability to hit much of the Soviet oil production with airstrikes, so Soviets would be hard pressed to neutralize this threat.
