From CounterPunch in May:
A reentry vehicle launched by an ICBM must absorb far more punishment than is the case with shorter-range missiles, and survive temperatures of 7000˚C. It took the United States several years to master the challenge of designing a survivable ICBM reentry vehicle,  and we have no solid information on the Hwasong-14’s reentry performance.
A nuclear warhead must be miniaturized to reduce the weight enough for it to be deliverable in a missile. As military technology specialists Markus Schiller and Theodore Postol point out, “It is unlikely that North Korea now has a nuclear weapon that weighs as little as 1000 kg. It is also unlikely that such a first-generation nuclear weapon would be capable of surviving the unavoidable 50 G deceleration during warhead reentry from a range of nearly 10,000 kilometers.”..
As the North Korean foreign ministry observed, “Not a single article or provision in the UN Charter and other international laws stipulates that nuclear test or ballistic rocket launch poses a threat to international peace and security.”
This is merely deep state neocons yanking our chain every couple of weeks to keep us afraid and confused.
Globalism has ensured that no nation possessing nukes will use them in anger. Most of the leaders have their loot stored with the UAE, who would seize it.
You can bet the sermon Sunday at every megachurch in Texas will concern itself with the fulfillment of end time prophecy.
The nuclear threat is a snake oil salesman’s best friend. Usually, they have to threaten hurricanes or other violence to fill the collection plate.
A system as important as Hawaii’s should be tested from time to time, especially after Pearl Harbor.
Just for fun, we’ve been stirring up trouble around the Syrian town of Armageddon.
Nobody is likely to nuke the USA because they’re too busy laughing.
The Russians and Chinese are into glider-launched multi-stage munitions which approach the target at Mach 5, delivering such kinetic energy that nuclear detonation isn’t necessary.
Nukes are messy, expensive and only useful to frighten children.
