Kubrick's vision seemed to be that humans are doomed whereas Clarke's is that humans are moving on to a better stage of evolution.

I think Mr. Clarke had a tendency to interfere too much with the activities of the CIA and our leadership at the senior level let him interfere too much. So criticism from him I kind of wear as a badge of honor.

According to Richard Clarke the former White House counterterrorism chief Bush was so obsessed with Iraq that he failed to take action against Osama Bin Laden despite repeated warnings from his intelligence experts.

I'm much better informed than Mr. Clarke ever was about the nature of the intelligence that was available again Osama bin Laden and which was consistently denigrated by himself and Mr. Tenet.
