These joint polls have been happening for years, and they are very valuable in comparing both sides' opinions of the peace process or a two state solution.
There were two questions asked, though, which were not well thought out. The responses are far more significant than they appear at first blush.
The pair of questions were prefaced with, "To what extent do you disagree or agree with the following statements regarding the experiences of Jews /Palestinians generally?" with the wording of "Jews" given to Israelis and "Palestinians" to Palestinian Arabs.
The first statement was, "I believe that the suffering of Palestinians/Jews is unique throughout the human history."
This question implies an equivalence between the Jewish people who have existed for over 3500 years and a Palestinian people who have existed as a self-defined people for, at the very most, a century. If the question was meant to show equivalence, it should have used "Israelis" instead of "Jews."
The answers:
It is impossible to make peace with people who are so detached from reality, and so wedded to the myth that their victimhood trumps all others since the dawn of time.
The next statement: "Since Palestinians/Jews are the victims of ongoing suffering, it is their moral right to do anything in order to survive."
The answers:
It is a poorly written statement for comparison purposes, because each side is likely to interpret it differently.
I'm not so certain if the same could be said about Palestinians. After all, they are taught that killing Israeli Jewish civilians is not only moral, but a legal right of "resistance" under international law, and they overwhelmingly support terror attacks against innocent Jews while the number of Israelis who support murdering Palestinian civilians is quite small.
The Israeli Jews almost certainly didn't have an expansive interpretation of what "anything" means. The Palestinians almost certainly did. Even so, far more Palestinians - nine out of ten! - say that anything is justified for their cause.
