According to [Michel Chossudovsky, a Professor of Economics, University of Ottawa for the Center for Research on Globalization (CRG), Montréal, Canada] in assessing the alleged links between the terrorists and the ISI, “it should be understood that Lt. General Ahmad as head of the ISI was a "US approved appointee". As head of the ISI since 1999, he was in liaison with his US counterparts in the CIA, the Defense Intelligence Agency (DIA) and the Pentagon. Also bear in mind that Pakistan's ISI remained throughout the entire post Cold War era until the present, the launch-pad for CIA covert operations in the Caucasus, Central Asia and the Balkans.
“The existence of an "ISI-Osama-Taliban axis" was a matter of public record. The links between the ISI and agencies of the US government including the CIA are also a matter of public record. The Bush Administration was fully cognizant of Lt. General Ahmad's role. In other words, rather than waging a campaign against international terrorism, the evidence would suggest that it is indirectly abetting international terrorism, using the Pakistani ISI as a "go-between".
