Sigh!...Precious and cute little flowers surrounding the wrong tree here. I put my own life on the line for the USA, as has my family for centuries now, and my wonderful stepsons, and I'd have personally been fine with conquering the entire middle east in '91, or most very certainly, in the wake of 9-11, and killing whatever batch lots of enemies as was necessary to ensure America's safety, no matter the number of such, be it wiping out entire nations or whatever. Any enemy that's bent on world dominance, to the detriment of America, (religion of "peace"/etc) must needs be thwarted, lest our own nation fall. It's just "politically correct" little fools who can afford to "think" otherwise.
Placing young Americans in harm's way, to play the part of supposed "police", into any area with people who, by reasons of us "playing nice", haven't felt themselves fully conquered, well...that's only "logical" to mindless politicians and fully flies in the actual face of human nature. Comparisons with Germany or Japan don't apply, since both those empires saw their cities incinerated, their people killed by the millions, and were left not even the slightest shred of doubt as to who "won"....But we nowadays just kill and allow our young to die for meaningless "sport", it seems.
To answer your question, I'll simply ask of you this: Since you supposedly, so much "care" about people...Would you willingly die to save, say 100,000 Iraqi people? if not/WHY not?...Aren't you all about "caring" for others? 😉
