Who started it:
Israel: 0%
Palestinians: 100%
In order for your conclusion to be valid, you would need to define the time over which you accumulated the data. Without a time reference, your conclusions have no merit.
Just for kicks do the data reduction again and this time start with one of the milestones dates in Middle East history. Perhaps the Balfour Declaration in November of 1917 or maybe, if you are real gutsy, begin accumulating your data early in the morning of April 9, 1948.
Tally your results and post them here. I will look forward to seeing them.
I think the time frame is correct for the present. You could go back to the 0 AD for example. But the proper thing to do now is to make the best of the current situation. I think the Israelis are doing a better job of that right now than the Palis are. I'm glad the statistics were so thorough. However the Palis can argue that the only effective weapons that they have are the suicide bombers while the Israelis have tanks, jets, etc. which are more discriminating weapons than the plain jane bomb. Bottom line, though, I still think the jews are doing better than the palis. Of course, neither side is completely in the right.
