Exactly. Soviet strategy relied upon many targets, and a great many warheads. In the Seattle area there are a number of targets worthy of a warhead or two: Trident sub bases at Bangor, Everett Naval Station, Boeing plants in Everett and Renton, Joint Base Lewis McChord, Yakima sat comm station, Hanford nuclear reservation etc etc. And those just ring the urban populated areas, and you haven't even begun to consider what your secondary targets might be. In the event of a concerted air and missile attack of nuclear warheads, the Pacific Northwest would be carpet bombed. And a terrorist bomb of any yield on any of these targets including civilian populations would ruin your day.
