In 1993 Osama bin Laden began speaking in detail to Muslim and Western journalists about his beliefs, goals, and intentions, and began publishing commentaries on these matters in the media.... While bin Laden's words have not been a torrent, they are plentiful, carefully chosen, plainly spoken, and precise. He has set out the Muslim world's problems as he sees them; determined that they are caused by the Unites States; explained why they must be remedied; and outlined how he will try to do so. Seldom in America's history has an enemy laid out so clearly the basis for the war he is waging against it.
