I was wondering how long it would take North Korea to publish photographs of their claimed thermonuclear warhead, and was surprised at the press release of 3 September 2017, and nuclear test soon after. According to some estimates, the yield was approximately 120-150 kilotons.
While I can’t comment on technical features of their warheads, it’s obvious that the fission warhead displayed in 2015 with an approximate diameter of 30 inches (76.2 cm) is a production device, and very likely uses manual insertion of nuclear components. The Defense Intelligence Agency stated on March 11, 2011 that the DPRK could deliver several plutonium based warheads.

That being said, while North Korea continues to threaten their neighbors and the US with nuclear annihilation, this is nothing new, and those of us who grew up during the Cold War were only six minutes away from Soviet SLBM’s, not to mention tactical rockets and missiles, and nuclear artillery at overseas locations. I personally never lost any sleep when I was stationed in Germany in the late '80's and early '90's despite Soviet grandstanding, Stasi trained terrorists, Warsaw Treaty Organization maneuvers, nor incessant propaganda from Pravda, Tass, and East German state media.

North Korea has achieved a threshold in the field of thermonuclear technology, and in years to come the world can only expect the DPRK to produce multi-megaton weapons for strategic use, and small diameter systems to include nuclear artillery, man portable atomic demolitions, and enhanced radiation warheads.
