What exactly does this incident have to do with counterintelligence? I think you are using that word incorrectly. I also don't understand what those linked incidents have in common. Sure, the US military isn't invulnerable and there is always risk associated with combat.
If the US military and government are anything like American companies, then they're good at marketing. Wait, I think with the military it's called propaganda.
I also grew up thinking a Stealth Fighter could never be shot down. It's invisible. No way.
Marketing/propaganda is an important part of defence. Having to actually fight will have costs. The real goal is to convince the enemy that there's no point in fighting.
