More than anything the trade embargo on the DPRK needs to be lifted, same with Cuba. The US trying to starve out populations into overthrowing their governments doesn't work, all it ends up accomplishing is fostering hatred for the US and further entrenching governments they oppose in the eyes of their citizenry.

Of course, the terror ends up being the goal of the US in the end anyways, once regime change fails it still ends up as a warning for anyone going against the US in general.

Rather than just assuming leaders of the DPRK are stupid, recognize the hand the DPRK in general has been dealt.
