This article summarizes earlier writings by the author on 9/11 and the role of Al Qaeda in US foreign policy. For further details see Michel Chossudovsky, America's "War on Terrorism", Global Research, 2005.
CIA support to Al Qaeda was not in any way curtailed at the end of the Cold War. In fact quite the opposite. The earlier pattern of covert support not only extended, it took on a global thrust and became increasingly sophisticated.
The "Global War on Terrorism" is a complex and intricate intelligence construct. The covert support provided to "Islamic extremist groups" is part of an imperial agenda. It purports to weaken and eventually destroy secular and civilian governmental institutions, while also contributing to vilifying Islam. It is an instrument of colonization which seeks to undermine sovereign nation-states and transform countries into territories.
For the intelligence operation to be successful, however, the various Islamic organizations created and trained by the CIA must remain unaware of the role they are performing on geopolitical chessboard, on behalf of Washington.
