Maybe he doesn’t think we will.
Look at the last four administrations.
NOBODY has given him even one indication, we would attack.
Agreed. What we are seeing is a twisted version of The Boy Who Cried Wolf. For years, NK has been the aggressor and provacator on the world stage. Nothing has happened to them militarily. They don’t think it will happen to them. NK is venturing into very dangerous waters and its leadership is oblivious to the consequences; this will not end well for them at all.
This attitude likely has effected their defenses in general. Despite having a large military, it is inexperienced and insufficiently trained. It has boosted of preparing for war but never fought a war. The Norks will not know what has hit them.
I think when the US and its allies strike, it will be at dusk. By the following morning, NK will be in complete disarray with command and control centers destroyed, not to mention their military bases/strengths obliterated.
