LOL - good one.
A high-five and a “jinx!” I think my word was “dogmeat,” though.
A liquid fueled rocket is best described as a "controlled explosion". There is a very fine line between controlled and uncontrolled however. A missile is a very complex machine with thousands of parts. A failure of any one part can compromise it's flight. The more parts there are the more things that can go wrong. Modern missiles are designed with the absolute minimum of parts since any redundancy would increase weight and lead to more complexity, both undesirable traits. I am surprised that the North Koreans have not transitioned to solid fuel rockets as Iran has done. The difference being the elimination of much of the failure prone machinery used to move the fuel and oxidizer from storage tanks to the engine.
US missiles (except cruse missiles) whether land or underwater based, are all solid fueled. Solid fueled rockets are as dependable as a rifle cartridge, light the fire and it goes every time. The only advantage that liquid fuel has over solid is the ability to vary the thrust in flight which is not worth the complexity. If you want to shorten the range of a given solid fueled missile you could program the guidance system to track a steeper ballistic trajectory rather than vary the thrust.
