Why can't more Asian countries have nuclear weapons? That's the question I want "45" to answer. It's not like North Korea is a new country inhabited by descendants of Native Americans who have a grudge against the United States! Who said only the nuclear weapon club is limited to European Americans only? This isn't an exclusive private golf club that limits and screens who can be a member. Plus, China and a few other non European American countries are already part of the club. Those non European American members aren't trying to sponsor a new Asian member. As a matter of fact they are trying to stay quiet even though they no what the deal is. They are saying to themselves, those American's don't want any more people who look like us in this club.
So what do the other members of the club do? They quietly help the wannabe member get their act together so they are fully qualified to join the club. So don't be surprised that any past technical issues North Korea was having were "fixed" quicker than expected. It's all part of the nuclear club game. The other members of the club benefit by any new country joining the club. It levels the field of play. It spreads the power with a nuclear butter knife.
