Depends on who shoots first. If it's "them," my guess is Vandenberg AFB, or the Bremerton SSBN base. Lefty blackshirts on the West coast have spoken openly of direct attacks on these facilities. In terms of the overall conflict, these people are the elite strike force of the dominant media culture.
I think there will be a leftist-Al Queda joint mission. The American leftists will do the recon and provide access, the AQ will come in last for the wet work.
