So...Trump has been in Office coming on three years....and you are trying to suggest the North Korean Missile program's successes are Trump's fault?
Now that is just plain stupid!
I suggest you read the article I linked in my post then get back with us on which American President you can play "Pin the Tail on the Donkey" about.
BBC reported Trump said he would walk out if the negotiation failed to be productive....and guess what....he walked!
