"Yet, Bin Laden never helped the Palestinians, over the years."

Palestinians don't muzzle their women and other cavemen activity.
Bin Laden is simply a false prophet, who has a bankroll. His values more align with rich spoiled American brats than Palestinians. Wacko environmentals might have cheered when the towers collapsed, but probably they were too concerned about all the environmental damage from the dust and how it would affect the sea gulls. Palestinians did cheer at the news of thousands of Americans dying, but that's because the uneducated are brainwashed into thinking that America was the source of their problems. Palestinians who had a clue weren't pleased with this attack, because they knew it wouldn't help them.
