This paper presents Arab public opinion trends on the Palestinian issue, through data collected by the ACRPS-conducted Arab Opinion Index. It assesses whether Palestine is a pan-Arab issue or one that concerns Palestinians alone. It also evaluates Arab regional attitudes towards recognition of Israel and towards the positions and policies adopted by some international or regional powers towards Palestine. The paper demonstrates that Arab public opinion strongly leans towards dealing with Palestine on the basis that it is a pan-Arab issue, not specific to the Palestinian people alone. It also shows that public opinion in the region is almost unanimous (at a rate of 88%) in rejecting any national recognition of Israel and that the assessment of Arab public opinion of regional or international powers in the region is determined by their policies towards the Palestinian issue.
