You are right in your analyses . This mind set of telling other sovereign nations what to do has to stop unless they overtly threaten this nation like Kim has done 6 times. Now it is time for him to denuke or we must preempt with nuclear annihilation. I would give him 48 hours.
North Korea’s nuclear program was aided by Iranian scientists; North Korean researchers and techs in turn worked in Syria until the Israelis destroyed the Syrian site.
No Saudis involved.
Kim’s stupid threats were aimed at getting aide from weak, easily scared westerners. He stopped that crap when it no longer got him the expected food aide or his army, but instead a bucket of trash talk from an unimpressed and unintimidated Trump.
