What is the theme in See No Evil: The True Story of a Ground Soldier in the CIA's War on Terrorism by Robert Baer?

The decline of the CIA is a theme in the book. As a new, young case officer with the CIA, Robert Baer was anxious to begin his career. He spent many years learning his craft and became proficient at recruiting "agents," gaining valuable intelligence for the US and learning to evade the enemy who was often just a few steps behind him. As the years passed, he became disappointed when he found a lack of support from his superiors back in Washington, D.C. Robert would eagerly report intelligence that he had gathered but would often learn that the intelligence went no where or was sometimes even greeted with hostility.
