That was not a reaction plan, it was an offensive plan. That's why they even bothered with targeting Soviet airfields. At the time the USSR had not yet developed an ICBM and so nukes would have been delivered by air. If it was a response plan, then targeting those airfields would have been wastes of nukes. The idea was to destroy their entire country and nuclear capability, before they could do anything. Remember, there's only one country that's ever nuked another country.
