"New York and Washington are still the biggest risks in the country. We come right behind them because of the special assets we have: the port, the airport and just the symbolism of so much of what they hate. In their rush to get back into the 7th century again, 21st century Hollywood is not exactly where they want to be." - Police Chief William J. Bratton

Sorry to burst your bubble Mr. Bratton, but "Hollywood" (aka the entertainment industry) is not one of the Islamic terrorists' motives at all:

The September 11 attacks were consistent with the overall mission statement of al-Qaeda, as set out in a 1998 fatwa issued by Osama bin Laden, Ayman al-Zawahiri, Abu-Yasir Rifa'i Ahmad Taha, Shaykh Mir Hamzah, and Fazlur Rahman.

The fatwa lists three main "crimes and sins" committed by the Americans:

U.S. military occupation of the Arabian Peninsula, U.S. aggression against the Iraqi people, and U.S. support of Israel.

The fatwa also specifically condemns the U.S. for "plundering" the resources of the region, oppressing the people by supporting abusive regimes in the region, and dictating policy to legitimate leaders.

It also opposes the presence of U.S. military bases and installations in the region, especially on Muslim holy land, which are used to "threaten" Muslim countries, while fomenting disunity and strife.

By a similar token, it decries the continued refusal to address the "occupation of Palestine".
