I shouldn't have sent you the raw data. That was a mistake, as you don't know how to interpret raw data, or even simple graphs. It is too much for you to wad through and you get confused by all the numbers and letters that jump back and forth between rows and columns and tabs and oh my.
Let me get back to you with a suitably juvenile source. I'll try to find something with bright colours and large lettering and no multi-sheet workbooks.
Edit: Here, this isn't too complicated for you. I know that it has alot of words and stuff but I think you can probably handle it. Let me know when you are done not reading it, as per the last source provided.

http://documents.worldbank.org/curated/ ... t-overviewAlternatively: Joshua Goldstein's Winning the War on War. This is a book but you can find adequate summaries online.
Alternatively: Go look at PIROs conflict datasets. I will gladly teach you how to use Excel if you want to do this.
Alternatively: Azir Gats "Is war declining - and why?" This one is good because it goes over about a dozen other studies, all but one of which claims that war is declining. First after the advent of the state, and then again over the past two centuries.
