You need to have a contrarian view. CIA needs many more analysts with better training and sharper skills. Years of bureaucratic rot, corrosion and corruption, hidden from successive administrations, Congress, and the public have sapped morale, lowered standards, etc. Too few CIA officers speak the languages in country where assigned. There too many problems, too many vested interests.
Officers are more interested in promotions than learning secrets.
In 1990, the CIA shut down its operations in the Soviet Union, except for liaison with the Russian services. A part of reason was if the CIA stopped targeting Russia it would cost CIA 500 overseas jobs for case officers. This is particularly true for all intelligence operations aimed at radical Islamic fundamentalist terrorists in the Middle East and around globe. Many radicals were activated by CIA's operation in Afghanistan during the 1980s that brought fundamentalists from many countries and trained, armed and energized their terrorism. Yet another irony is that Agency seems totally incapable of controlling or penetrating the Frankenstein of its own creation.
