Comment: Threatening North Korea with regime change would do nothing to reduce or eliminate threats from North Korea, but it would confirm the regime’s leadership in its conviction that it needs its nuclear weapons and missile programs to fend off an attack. Nothing makes a regime obsessed with its own survival less likely to compromise or negotiate than vowing to overthrow it, and besides attacking North Korea there is nothing that makes a North Korean attack more likely than making their government believe they have nothing left to lose. 
 Kim is quite aware that if you give up your weapons like Ghaddaffi, you will be killed.
