The hope was to bankrupt the US, forcing them to withdraw from the ME (especially Israel and Saudi Arabia), like what basically happened to the Soviets in Afghanistan. This did not happen.
Sure the whole debacle did cost US a lot of money, lives and perhaps prestige. But that does not mean al-Qaeda achieved their goals. The US is for better or worse even more entrenched in the ME, with bases in Afghanistan and Iraq. And Israel and the Saudis are still there.
Some tend to think that anything which is bad for the US means the terrorist are winning, because "they just wants to hurt us". But it doesn't work like that. Terrorism is a tactic employed by certain groups to achieve certain goals. It is possible that both parties are weakened by a conflict.
