FILE - In this file photo from Aug. 27, 1992, a year after the first Gulf War, U.S. President George H. Bush speaks at a White House news conference, wherein he announced a "no fly zone" over Iraq in which Iraqi warplanes would be shot down if they flew below the 32nd parallel. Though U.S. jets flew over the vast Iraqi desert every day for more than a decade, they could not prevent then-dictator Saddam Hussein, a Sunni Muslim, from persecuting and killing hundreds of thousands of Shiites whom he viewed as a political threat to his regime.
