At the end of the day the US.mil is spending billions to trillions of dollars. I'm not exactly sure what you mean by lose your luster, but becoming part of the military industrial complex is generally a way to bury yourself in deep piles of gold.
Unfortunately, no deep piles of gold without deep piles of corpses. It is inevitable, though. Prompted by the US military, other countries have also always pioneered or acquired advance tech, and I don't see why AI would be any different: Never send a human to do a machine's job is as ominous now as it is dystopian as machines increasingly become more human-like.
