But Palestinian support for Al Qaeda, Osama bin Laden and suicide bombings remained high even as Arab countries turned against them.
This Pew Research graphic shows that Palestinians were more enthusiastic about Al Qaeda than citizens of any Arab country, and while their support waned over the years, they continued to be the most extreme supporters of terror among Arabs in the decade following 9/11.
In 2014, the most recent poll I can find, Palestinian Arabs were most supportive among world Muslims towards suicide bombings - by far.
And even then, three years after Osama Bin Laden was killed, a huge proportion of Palestinians continued to support Al Qaeda - more than any other Muslims:
One doesn't see questions about suicide bombings and support for Bin Laden being asked by international pollsters any more, possibly because they make Palestinians look so bad. But even this year, a majority of Palestinians support "armed attacks" against Israeli civilians, and there is little reason to think that they distinguish between "martyrdom operations" and any other attacks on Jewish civilians.
Bin Laden lives on - in Palestinians.
