After success in ICBM & H-Bomb, what is the correct Next Step for NK by a standard military theory? The answer = CRUISE MISSILE One can consider a Cruise Missile as a Drone carrying a Warhead, and in this case H-BOMB. Iran captured USAF drones and developed many versions of their own.

Why Cruise Missile? 1st of all, is surprise element, and which to complement ICBM / IRBM, which THAAD & Patriot etc can detect from a long distance, and calculate a generally predictable trajectory & approx time & location of impact, and hence advance warning plus interception. Cruise Missile generally flies BELOW RADAR & Covered by Terrains. It does not have a big bright hot rocket flame, and it resembles just a low flying aircraft, except there is no pilot inside. 2ndly, Cruise missile can be made easily and cheaply. It has a very very low entry hurdle, it takes only basic aircraft technologies instead of rocket science. If you remote control or auto-pilot a World War One aircraft taking off from a farm road, carrying a bomb it is already a Cruise Missile. The famous 911 attack hijacked Boeing 767s and used them exactly as cruise missiles. Then as you can see, THEY CAN BE VERY CHEAP to make. 3rdly, Cruise missile are extremely flexible. As you have more budget, more resources and creativity, you can Really make Some Extremely Nasty surprises, there are too many areas that you can experiment. The variety of cruise missiles range from submarine launched, ship-launched, aircraft-launched, truck launched, you can have sea-plane taking off from any pond lake or sea, you can launch from any trucks or pickups, you can launch from HDB rooftop, you can have helicopter version, vertical take-off, you can have cruise missile that will do landing and take off with remote control or per-programmed, e.g. land and hide from detection or crotch somewhere to ambush, awaiting for a single or opportunity to attack. It is possible to make Cartoon Transformer cruise missile that can fly and land and transformed into a land vehicle and move on land and then take off again like a drone, just to penetrate some defense areas, not require very high technologies. They have designed many interceptions and counter-measures to intercept or defend against Ballistic Missiles like ICBM IRBM SLBMs etc, but quite hard to make much to defend against cruise missiles.
