Frankly speaking North Korea had offered to give up their Nuclear Weapons in exchange of United States assuring them of no first use and other such conditions and of course Financial help to the nation so that it is not betrayed by any of the parties including United States to the negotiations. But, United States rejected all its offers. On the other hand Iran is long way off from having Nuclear Weapons as well as having ICBM's whatever the warmongering experts say. Therefore, they are not capable of attacking Europe and therefore, are no threat to United States. Also Iran knows that it will be destroyed by Israel if it attacks it. While Israel is the only one with Nuclear Arsenal in this region and nobody talks about that. It is only Israel which is talking of Iran of a threat for its own 'selfish' interest and pushing the Trump administration towards deep state so that the Nuclear deal be cancelled for no valid reason. We are living in dangerous times that is for sure.
