I think it is not surprising if a technologically capable resourful developed nation is resorting to use advanced new weapons. I would prefer not to say US here as that is not important. Overpowering and Defending itself has been a predominant part of human nature since the evolution. Human being fought and defended itself from natural calamities, ferocious animals, hunger, from their own counterparts when they started settling down after they resorted growing crops to fend themselves. As the time elapsed the weapons and ammunition kept changing its form from fist, teeth, nails, poison, stone, metal, guns, warheads, explosives in all forms including nuclear bombs and now AI. What didn't change are attack and defence, which basically emanates from inbuilt 'fear' of remaining undefended, vulnerable! No wonder sooner or later some countries would develop antidotes to defend themselves from AI weapons! AI driven weapons or anything else in future, it would be unstoppable! It's something to do our 'basic insticts' over which any religion on this blue planet could only temporarily control!
