An elite U.S. Army study center had devised a plan for enforcing a major Israeli-Palestinian peace accord that would require about 20,000 well-armed troops stationed throughout Israel and a newly created Palestinian state.
The SAMS paper attempts to predict events in the first year of a peace-enforcement operation, and sees possible dangers for U.S. troops from both sides.
Of the MOSSAD, the Israeli intelligence service, the SAMS officers say:
"Wildcard. Ruthless and cunning. Has capability to target U.S. forces and make it look like a Palestinian/Arab act."
The amazing thing about this is that this story was reported in the Washington Post on September 10, 2001.
This is probably the most comprehensive compilation of facts regarding Mossad planning and actions regarding 9/11 I've ever seen.
