6 Feb. Senior Executive Intelligence Brief (SEIB): The discovery of multiple terrorist plots since October shows an energized international "jihad movement" is raising the threat to U.S. interests, particularly in the Middle East and Europe.  Most significant spike in activity since the time of the Millennium.  Stems in part from changes in bin Ladin's practices.  To avoid implicating himself and his Taliban hosts, he has allowed cells in his network to plan attacks more independently.

"Based on a review of all-source reporting over the last five months, we believe that UBL will launch a significant terrorist attack against U.S. and/or Israeli interests in the coming weeks.  The attack will be spectacular and designed to inflict mass casualties against U.S. facilities or interests.  Attack preparations have been made.  Attack will occur with little or no warning.  They are waiting us out, looking for a vulnerability.

30 Jul. U.N. Security Council adopts Resolution 1363.
