More Specifics.
The stated grievances of the bin Laden network fit a pattern familiar to students of Islamic activism over the past two centuries. In a fatwa released in February 1998 (and echoed last week by the Taliban), bin Laden and leaders of extremist groups in Egypt, Pakistan and Bangladesh specified that their war was a defensive struggle against Americans and their allies who had declared war "on God, his messenger, and Muslims." The "crimes and sins" perpetrated by the United States were threefold. First, it had "stormed" the Arabian peninsula during the Gulf War and continued "occupying the lands of Islam in the holiest of places" (i.e., Mecca and Medina in Saudi Arabia); second, it continued a war of annihilation against Iraq; and third, it supported the state of Israel and its continued occupation of Jerusalem.

Al Qaeda's main goals:
Remove Western influence from Islamic lands. In practice, this means eliminating American military, cultural, and political influence from predominantly Islamic countries in the Middle East and Central Asia.
Destroy governments in Islamic lands that are supported by and linked to the democracies of the U.S. and Western Europe and that have made peace with and recognize the legitimacy of the state of Israel.
Establish orthodox Islamic regimes throughout regions where Muslims are the majority of the population and put into practice the strict tenets of Shari'a law.

We have some bright people here. Instead of generalized commentary how about tackling a specific situation, such as the grievences of the folk that attack that USA?
