Perhaps everyone posting in this thread can give their military experience before they step up to question the practices of someone who has served.
Shades of Heinlein's Starship Troopers!
Then again, Heinlein didn't have to go far to find
a source for what his story was suggesting.
Be very careful with attitudes of exclusivity because they do have a way of going much afar into a nightmare scenario when the other shoe is allowed to drop!
BTW: The hecklers were dead wrong, The debate is over civilian policy at the highest levels and not about the average soldier. If the soldier made any mistake, it was only repeating the line given by the higher command thanks to civilan policy makers that in the opinion of many, has become more and more discredited. The hecklers could have easily made a counterpoint and still maintained all degree and manner of respect for the soldier as a individual person.
But take heart, in out completely friend'd up world we live in, those same mindless college grads will go on, you'll elect or appoint them to gov't to serve in your interests and then one day they'll secretly conspire and draw up invasion plans of yet another country who made the mistake of being born and living on top of our resources or otherwise just decide to live in their self interests rather than to the benefit of ours!
