Atr0creep, I don't mean to be cynical isn't your statement somewhat akin to saying "I don't mind going out in the rain, provided there's no water involved?" I really don't see how powerful people are ever going to absent from the decision to go to war. We have the luxury in our countries of trying to see that our personal and tehir personal interests coincide, but you're never going to cut them out entirely. And, as we previously said, you can't run an army using people who fight when they feel like it.
Incidentally, I remembered this afternoon that such an Army was tried at least once, in the counter-bolshevik struggles in Northern Russia around Archangel just after ww1. Really didn't work. They got comprehensively tonked.
