To some extent, behind every major official organization there are the rulers of their own feudal kingdoms.
The three founders of the NW Organization were such figures.
The destruction and retaliation plan was a doomsday scheme where, if the three major families were ever to face the crisis of annihilation, artificial intelligence programs would take control of the most hidden deep-sea launch wells. Without hesitation or concern for collateral damage, they would send high-yield nuclear warheads directly to their attackers, ensuring mutual destruction.
The combined yield of these nuclear weapons was staggering enough to destroy the coastal city cluster wrapped by mountains.
This land, without the three major families, would have no purpose for sustaining life!
