How To Limit Warfare?

The title, "How To Limit Warfare?" pretty much sums up my problem at this point. I have so much I can research. I have a vast amount that I am interested in. I just have to narrow it all down. As I was doing some preliminary research on the overall military tactics and technology changes I continued to come up with a lot of the same data hits. Most of them had to do with U.S. Military Drones and their uses. I know for example that a few years back the United States began arming our unmanned drones. The once reconnaissance platform is now one of our "go to guys" for taking out remote or dangerous targets. As I read through some of these sources I began to see a trend. A lot of people from around the world are chiming in on how these new "death drones" are used. I think that I too would like to "chime in". I believe I am now planning on focusing my research on these new unmanned aircraft, their uses, their armaments, and how they are used. I might go a bit farther into how they are used AND why. I'll have to decide which side of the ethical dilemma these "death from afar" type weapons cause. In any case it looks like a lot of research and even more thinking before I begin writing my first drafts for my final paper...
