Investigate the Henry A. Kissinger Roundtable on Terrorism conducted by the CFR. Note especially the involvement of John O'Neill, Jerome Hauer and Maurice Sonenberg. Sonenberg was Vice Chairman of Bremer's National Commission on Terrorism.
See also Carter, Detuch and Zelikow's Catastrophic Terrorism. See here as well.
The WTC Privatization Agreement is another big clue. It involved Ronald S. Lauder and Larry Silverstein, among others.
