Pakistan is a terrorist nation. It is just surviving because USA still want to use it as a supporting base for Iraq nad Afghan operation.
North Korea, never was found behind a terrorist attack else where, They are oppressive and dont respect human right of its people, By the yardstick used to put sanction against North Korea, Pakistan would have gone under sanction long back. Because it is killing freedom fighters of its occupied territory Baluchistan, and Almost every terrorist attack happened across the world has some or the other way connection with Pakistan,
Pakistan may be able to escape from global sanction as a terrorist nation for couple of years, But world would soon realize the truth, that Pakistan is a terrorist nation.
