I just hope that if there are any Freepers in San Franweirdo they get out in time.
Ain't gonna happen. If Kim Jong Il were to try to unilaterally strike a US city with ONE nuke, I strongly suspect that the dissenting factions in his own government would bring his regime down in a flying tackle. Il may be a nut- but there are people in his upper echelons that know exactly what would happen. I don't believe that Kim is blind to that, either.
China does exert some influence on North Korea as well- the last thing the PRC wants is South Korean and US troops walking around on the Chinese border in their MOPP-4 suits, picking at the ashes.
San Francisco may be infested with weirdos from everywhere else- but it (and a little town named Gasquet up north) share the distinction of being 'home' for me. I'd hate to see it get flattened. :-)
