Israel is just one thing,
Israel is a major thing, and I never said it was the only thing, I only take exception to your assertion that it's not a contributor at all. Whenever you claim that you lose all credibility on this issue. Osama bin Laden listed as his grievances:
1) Support for Israel
2) Presence of American troops in Saudi Arabia
3) Sanctions against Iraq
We no longer have troops in Saudi Arabia and we didn't have troops there before 1991. We no longer have sanctions on Iraq and we didn't have sanction on Iraq before 1991. However, the one constant over the last 65 years has been our support for Israel, which since 1967 has been blind and uncritical.
I once saw an Arab, Ivy League educated, westernized journalist on a political talk show say that Osama bin Laden champions the Palestinian cause because he knows it's the one issue that resonates even with secular Arabs like him who despise bin Laden and everything else he stands for. It resonates with Arabs like John Sununu who in 1988 angered AIPAC when he was the only governor of a U.S. state not to call for repeal of the UN General Assembly Resolution 3379 which defined Zionism as racism. It resonates with Arabs like Darrell Issa who was the only U.S. Congressman to visit Lebanon during the 2006 Israel-Hezbollah War, has called Israel an apartheid state and who was once the victim of an assassination attempt by the Jewish Defense League. And it resonates with Arabs like George Mitchell who quit his job as Obama's envoy to the Mideast when he realized that Obama would never let him put pressure on Israel. None of Al Qaeda's other objectives have any broad resonance whioh explains why their candidates do so poorly whenever they run in elections. The vast majority of Arabs/Muslims have no interest in living under 7th century Islam.
but if we didn't support Israel 9/11 would have happened
You don't know that, all you're doing is engaging in idle specualtion and conjecture. Without our support for Israel, it becomes harder for Al Qaeda to recruit and there's no denying that.
You're an idiot if you think otherwise.
And you're a Likud-sympathizing, Israel-firster trying to justify and rationalize America's support for an apartheid state.
