There is the effect of military presense creating more from the opposing forces. It happened with Vietnam too. I always thought it was very arrogant of the US to go into Iraq. I thought, or hoped they would just go in and become better support for the UN and what that effort was, instead we got bombs flying.
As for Steve's take that we shouldn't say soldiers are heroes or villians I'd like to elaborate. I'd say the same, to not judge the acts the soldiers have to take while "under the influence" of the chain of command and being in survival mode. Weather those actions are heroic or villianous is for the military higher ups to answer to.
Now, for every soldier out there, they are individually heroes, hands down. What they go through I'll never know and I'll look for all the peace I can find in hopes it helps in some metaphysical way.
Another thought I had was that when a soldier agrees to go into training and kind of gives up some freedom to be effective and to be able to operate in the military ranks - that agreement is sort of like everyone that incarnated. We gave up our freedom in the spirit world and put ourselves into a body. So in a way a soldier's path is like physical incarnation and also somewhat spiritual because of this. When they come home and get out of the military it's like a death. And they have to re-adjust and hopefully bring the freedom back into their own life.
