Drone piolots have no doubt done somethings history won't look kindly on but so has basically every fighting man using whatever technology and tactics. Sure maybe some just do it for the pay check or lack of other options but most of the people that enlist in our volunteer armed services have some conviction about defending the nation.
I will challenge, "most". How would we know if their motivation was the defense of the nation or if they just needed a job and their best option was to enlist? And defense of the nation from what? The US hasn't fought a war in defense of the nation since the 19th century.
Let's stop romanticizing the military. This isn't GI Joe who was drafted off his daddy's farm to go fight the Fuhrer. This is a "professional military", remember? And there's a word for professional military. Mercenary. Just look at how eager these guys are to go work for Blackwater, or "Xe" or "Academi" or whatever the private contractor army is calling itself today.
I'm kind of surprised that the same people who look sideways with suspicion at anything Big Government does also romanticize the enforcement arm of that Big Government by becoming military groupies or police buffs. Every member of the military and every member of every police force in the United States fits the dictionary definition of "bureaucrat", plus they get to use deadly force. Remember that the next time you hear someone talking about those damn "government bureaucrats".
