Thanks Jamie! That explains it better for me. It's a way of looking at it that I hadn't even thought of.
I recently saw the documentary "Sir, No Sir!" about the soldiers in Vietnam and stateside who opposed the war. They fought from within the system itself to end the war. At times, they simply refused to fight or be deployed, others wrote and distributed anti-war newspapers, even the men who spied on the VietCong's telephone and radio calls would translate incorrectly, to keep civilians from being bombed and subvert the military's plans. It was interesting, and it was a movement I knew nothing about. (It was also pretty cool that Jane Fonda came to speak after the movie, with a couple of Vietnam vets and recent Iraq vets!)
Perhaps those enlisting could be seen more as wanting to serve their country, but opposing an unjust war? Perhaps they, too, (supposing they are even accepted into the military despite don't ask don't tell could work from within with other soldiers who are against the war?
I definitely see both viewpoints, and being the Libra that I am, I find merit in both sides of the argument. Thanks for the further explanation.
