If your attitude is "they're all guilty" you shouldn't even be IN the military. Is there any way to report statements like that to your commanding officers?
Tell ya what, how about
you go try to fight an indigenous force, without benefit (for us) of an identifiable uniform, who blends in just about perfectly with the local populace (and therefore cannot be readily told apart and culled out.)
Iraq/Kuwait in 1991 was no more amusing than Iraq and Afghanistan now - the primary difference is that we weren't fighting the Talibs in Afghanistan in 1991 (just Hussein and his Republican Guard.) Throw in local sympathisers, and you have trouble looking for places to happen!
Spend enough time dealing with that sort of situation, and you
will start thinking "They're all guilty" - as will your CO, and any other personnel regularly in the field. This isn't necessarily a bad thing - it's that sort of paranoia that can keep you alive and get you home again.
Much has changed in warfighting since WWII - Korea was the beginning of the new trend in warfare, and it was only solidified in Vietnam. I've known plenty of guys who were over in the Big Asian Vacation, and many of them say the same thing - somewhere about halfway through the tour, they came to the realisation that bombing them back to the Stone Age might not have been such a bad idea. In 1972, Nixon was doing just that when he authorised Linebacker I and Linebacker II (carpet-bombing of North Vietnam.) We had NVN on the ropes with those, and we would have brought them to heel if we had continued - probably would have won the war with Linebacker III. And this was
after the PR victory of NVN granted by Tet 1968!
Now, might I ask on what basis you form
your opinion? I'd like to know - if it's an erroneous premise, perhaps we can correct it.
