Yes and no. They attacked us because we have supported Israel with massive foreign aid and votes and vetos in the UN. Arabs see the relative sizes of the two countries and assume Israel is doing our bidding. They do not understand that in a democracy an organized minority can wield great influence.
Two points:
1) The US and Israel are not fighting the same enemy. We are fighting a band of Islamic maniacs...the Israelis are locked in a tribal war with the entire Palestinian people. While Osama's crowd has no legitimate grievance against the US, the Palestinians have plenty of legitimate grievances against Israel. Every civilized person on the planet believes that Osama is evil. Most of the people on the planet have sympathy with the Palestinians, even if they disagree with some factions' terrorist tactics. This false equation of the situations is one of the underlying propaganda falsehoods behind this upcoming Iraqi war.
2) While you may say that the 9-11 terrorists didn't attack america because they hate Israel...that certainly isn't what they say. Osama clearly stated numerous times that his reasons for the attack were:
1) Our support of Israel
2) Our troops in Saudi Arabia
3) The sanctions against Iraq
While I deny that any of these are legitimate justification for what he did, your assertion that our support of Israel was unrelated to the events of 9-11 is clearly false.
Well,on one hand that's true and on the other,there is reason to believe that our support of Israel was related to why they attacked the World Trade Towers. Osama bin Laden stated,shortly after the attack,that America was hated because Americans had 1)a consumerist mentality,2)a poor moral value system which Americans sought to impose on them,and 3)a knee-jerk response to support Israel,in all matterss related to the mideast.
I remember reading his words as everyone was frantically putting their spin on why we were attacked which usually ended up with attributing it to their jealousy of our standard of living and our position as a world power.
I wondered why we did not at least look at why he said they attacked us,but sadly I realized that we,as a nation,are not introspective.
