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.
