Pulling out of the nuke agreement because of a mere criticism at an irrelevant forum is not a reason good enough for North Korea to start its nuke weapons program. Its really frivolous. Wonder what it wants to bargain for now. There is hardly any credibility of that regime, so wonder for how long the US, South Korea and Japan keep giving into this regimes demands. There will be talks and maybe the North will stop its nuke program. But there is no guarantee if the North will once again pull out of it if someone in the US admin criticized the Dear Leader's pants!!
