@Fisherman: I agree North Korea is unlikely to start a nuclear war with the US, but if they could nuke most US cities the US would pretty much no reason to prevent them from launching an attack on South Korea.
If you throw nukes into the mix u basically don't know what is gonna happen. If NK nukes South Korea (or nuke South Korean troops on the battlefield), the US probably have to go nuclear too to win the fight, in which case nobody know what china is gonna do when nukes are flying on their southern border. it will be crazy. which is why a conventional war now against North Korea is a much, much better option than a North Korean nuclear rocket.
Liberals don't understand that and pretend that a "wait and see" attitude is not the same as CHOOSING nuclear rocket. the wait and see crowd might as well spare us the grief and send them the nuclear rockets from our stockpile lol.
