Seattle is the least major target in that area of the state.
1. Bangor Naval Submarine Base - "Bangor Sub Base manages the third largest collection of nuclear weapons in the country, with approximately 1,700 Trident missiles either stored at its hill-top depot, or inboardr its fleet of eight Trident submarines which still roam the seas on secret missions."
2. Everett Home Port (Nuclear Carrier Base)
3. Bremerton Naval Station (Nuclear carrier and attack subs)
4. Whidbey Island Naval Air Station
5. Mchord Air Force Base
6. Fort Lewis - 25,000 soldiers
7. Boeing - Seattle
8. Boeing - Everett
9. Microsoft
10. Seattle
Basically you need to be really North of the border (like almost Alaska) to not feel the effects of the hundred or so nuclear weapons they figure are aimed at the Seattle area alone.
Basically were screwed.
edit: Oh yeah I forgot if we did have a big ole nuke exchange and Russia decided to expand it territory guess what their route is going to be? Yep across the Bering Strait into Alaska, Canada, and then the good old lower 48. Stopping to make a "grouchy but well qualified prehospital care provider" their bitch. Personally if it gets anywhere near what your talking about this grouchy well educated Paramedic will be in Mexico. What the hell is there to nuke in Mexico?
