Difference is mate these are not nuclear ballistic missiles and all North Koreas are.. Also North Korea shoot them in to other nations waters and over their countries. BIG DIFFERENCE.
Solid rocket motor play major important role for boosting missile to hypersonic speed were its transition to scramjet operation And the thrust produced by the engine is absolutely overcome the drag force which drains the kinetic energy and the goal to fly hypersonic speed.
This doesn't have scramjets and USA is developing Hypersonics with Australia and has been since 2002 and Australia has world's fastest scramjet at Mach 14.
US does test after test and it is announced with great pride. N.korea does one and USA has a hissy fit like they exploded a nuke over manhattan.

With luck, the USA may have a hypersonic combat ready drone in 10 years.
