The countries with ICBM*capability (meaning the ability to send a nuke anywhere within 15 min.) are Russia, the United States, France, the United Kingdom, People's Republic of China and (likely) Israel.

Plus in 1998 NK sent a missile OVER Japan. In June the tested a missile that could reach Los Angelas but it failed.

I don't think that we can win a war without an ivation at some point. Maybe we can I'm no expert. However, we would need to make sure that any NK weapons don't get "lost" during the bombing and bought up by terrorists elsewhere.

*Intercontinental ballistic missile
