I'd be amazed to see North Korea get a nuclear submarine or ship past..say..Okinawa before we detected them and had planes in the air (luckily we have an airbase in Okinawa).
Either way, we can't invade North Korea. It has so many lovely mountains and a million-man standing army with decent technology (MIGs, tanks, etc.).
Correct.
Nonetheless, I think we unnecessarily provoked them into accelerating their nuclear program and have been too uncompromising in negotitations to end that program. Not to make excuses for Kim Jong-il, he's pond scum, but the problem could have been mitigated.
