haven't been following this thread much, so sorry if this has been pointed out.

Given a choice, North Korea.

Bomb Iran and you upset lots of people in lots of countries due to our old friend religion. Bomb North Korea and who else gets upset? err... not even the Chinese who are fed up of propping them up.

Hopefully the above ironic comments are taken that way, as I hope the original post was ironic, but amazing how many people, especially in The United Confederate States of Dumbfuckistan actually think this as more than an academic question....
