I'm no expert on this, so maybe I got something wrong, but I think it's about these issues: 1) The extreme in the Arab world is against the process of globalization, which in their eyes is led by the US, because it endangers the Arab consolidation. 2) You have to understand that the arabs see themselves as one nation, so if the US is fighting in Iraq, they don't see it just as a war/embargo on Iraq, but as something against the whole arab nation 3) Last but not least, US is conceived of as Israel's friend and ally.... btw - it's not necessarily palestinians..it could also be Lybians/Iraqu/Iran and so on.... Plenty of extreme militants out there. Again, sympathize with you guys, love S.
