1 - Al-Qaeda does seem to be affected by Arab criticism. Which means that if the "moderate" Arabs had shown the same outrage after 9/11 as they are now for 11/9, Al-Qaeda might be severely weakened by now.
Unfortunately, we know that most of the Arab world was not unpleased by 9/11.
2 - Notice that this statement doesn't complain about "Zionists" in "Palestine", but "the presence of Jews." Let's not hold our breath to see Arabs protest against that, and trying to educate Zarqawi about the centuries of peace and tolerance between Jews and Arabs they always try to tell the West.
3 - It is pretty obvious that when Islamofascists say "Crusaders" they mean "Christians."
CAIRO, Egypt — In an apparent response to Jordanians who took to the streets to call for its leader to “burn in hell,” al-Qaida in Iraq took the rare step Thursday of trying to justify the triple suicide bombings that killed 56 people, mostly Arabs.
Earlier Thursday, the group posted a Web statement claiming responsibility for Wednesday’s attacks. Then a second al-Qaida statement appeared on the Internet “to explain for Muslims part of the reason holy warriors targeted these dens.” That statement appeared after Arab-wide expressions of outrage.
“Let all know that we have struck only after becoming confident that they are centers for launching war on Islam and support the crusaders’ presence in Iraq and the Arab peninsula and the presence of the Jews on the land of Palestine,” the group said.
