as you've pointed out, the events in '53 has it's own influences. I'm just saying that, in discussing "the events LEADING UP TO 9/11, including a thorough examination of the role played by our foreign policy over the last 50 years" that the "marshal plan to rebuild Europe and the rebuilding of japan, the Berlin airlift, the defense of south Korea" aren't really pertinent to why some middle eastern religious nut-jobs would want to attack us on 9/11.
as to your question, US foreign policy is responsible for US involvement in Iran and the middle east from 1953 onward when we started meddling in their internal affairs. Prior meddling by the British and the USSR aren't the result of US foreign policy.
