Undoubtedly these are contributory events, but the underlying hatred of the USA is based on that most useful (to Democratic and other demogogue politicians) of all emotions - ENVY. The Islamic fundamentalists hate us because they envy us. If we never intervened in any other country they would still hate us because they hate wealth. They hate accomplishment. They hate seeing success. Their hatred is based on the envy felt by the self-made loser for the self-made success. This is shown by the fact that their primary and most deadly attack was on the most visible symbol of accomplishment in the USA - the WTC. In this regard they are exactly the same as the supporters of Al Sharpton, Maxine Waters, David Dinkins, Yassir Arafat, the Clintons etc. These Democratic tyrants are marginally more subtime in their attack on success and accomplishment in that they want to destroy it via taxes rather than fire, but the emothion is the same.
Now as to whether the fundamentalists would hate us enough to kill 10000 innocents and kill themselves in the process is another story. My guess that without the constant stirring like Slick Willie's "wag the dog" attack on the Sudan, and our constant politically motivated (Jewish vote) support of Israel they may not have been motived to commit Tuesday's atrocity, but they would still hate us because we are what they are not We don't live in squalor. We have a few freedoms that the fed hasn't gotten away to abrogating (yet). Those who live in poverty because of their own stupidity and lack of ambition hate those who work to get ahead. You see it when you see who elects Democrats that promise wealth redistribution. You see it when you see who supports "reparations." Islamic fundamentalists are human. Their hate filled politicians manipulate the same base nature of humanity that the race-baiters and socialists use in this country to get and keep power.
