US and President Trump, Put up or shut up. The United states should stop making noises about north Korea nuclear programme. If the CIA look properly they will discover that north Korea has been used as a testing ground by it neighbours.
Those countries that refuses to implement the UN sanctions are use North Korea as a bate for the United states. The US should allow South Korea and Japan to develop their own nuclear programme or weapons that can reach North Korea and it neighbours capital cities. They should carry out nuclear test every week just like North Korea.
North Korea neighbours are responsible for it nuclear programme and they are the only countries that can stop North Korea nuclear programme.
