I have seen a number of programs that were stand alone investigations about Usama bin Laden. They pointed out that Usama was first brought to live and recieved all the initial training from the US. The US goverment used him against the USSR forces in Afganistan and later used him to pressure Kuwait.
On another note, Iraq has been quite close to the US, they have been "allies" in some sort until the Gulf war of course. Once again the US helped Iraq to develop chemical weapons that were used against the Kurds in Iraq.
So basically their own weapon back fired againts themselves, I believe they deserved the terrorist attacks that were made against them ( I stress US as a state deserved it, not the people that have died, they were just unlucky to pay for the mistakes of their goverment ) The USA brought terrorism to life, first by simply sponsoring it and then by bringing the chaos of war to Afganistan and Iraq.
