"George Tenet has been the director of central intelligence since 1997, time enough to have changed the Agency's culture. He has failed. He should go"

This quote by Richard Perle is a criticism of George Tenet, the director of main intelligence given that 1997. Perle thinks that Tenet has had adequate time to alter the culture of the Agency, but has actually stopped working to do so. He thinks that Tenet ought to resign from his position as director of central intelligence. This quote implies that Tenet has not achieved success in his role as director of central intelligence and that he must step down from his position. Perle thinks that Tenet has not been able to make the needed changes to the Agency's culture which it is time for him to leave. This quote is a clear indicator of Perle's frustration with Tenet's efficiency and his belief that Tenet ought to no longer be in his position.
