This one's about revolution--obviously--and how we have too many wars, and that once we've destroyed ourselves with war and fighting, we'll just have neither peace nor protection, and much more poverty. Revolution seems to relate to people starting wars for some thing, but in this case, it's more like a new way of living--and I don't mean new technologies and hybrid cars and going green, although those things should be very welcomed in our society . The Back Door is basically about the fact that we need this revolution of a better world, but we'll just toss both that and our used-up wars and weapons out the back door. We'll just forget about it...until it creeps up behind us, once more. Enjoy!
