Robert, absolutely not, no offence whatsoever. Most only know/believe what the newspapers/media print/broadcast. War and especially guerrilla-type wars are atrocities in and of themselves and troops, even the best trained become callous. When you can't tell friend from foe and friends are killed/maimed by booby-traps, 8YO shoeshine boys, mothers with grenades under their babies, and worse your moral compass tends to shift. IMHO, US troops have shown above average restraint in the vast majority of conflicts.
