Endorsing Al-Qaeda terrorism: The Norwegian organization Fafo found, in a face-to face survey with 1849 respondents aged 18 years and above in the West Bank and Gaza in the period November 21-10 December that "Support for Al Qaeda actions in the world includes 65 percent support to Al Qaeda actions in the USA and Europe, 32 percent support for Al Qaeda actions in Iraq and 13 percent support for Al Qaeda actions in Jordan." Nearly 2/3s of Palestinians, in other words, support Islamist terrorism against the West, or more – but not hugely more – than the ½ of Muslims world wide whom I estimated in 2002 "sympathize more with Osama bin Laden and the Taliban than with the United States." (December 22, 2005) Dec. 26, 2005 update: These views did not come out of nowhere and Palestinian Media Watch documents the many mechanisms by which the Palestinian Authority's "religious leadership has been presenting its war against Israel's existence as merely one part of its global Islamic war being fought against the Christian-Jewish West." Also, PMW makes this important observation: "What is striking … is the willingness of Palestinians to turn against even the Western countries upon whom they are so totally dependent."
