In the Persian Gulf area, Iraq remained a problem. In June 1993 two U.S. Navy ships fired Tomahawk missiles against the headquarters building of Iraq's intelligence service in Baghdad in response to evidence of a plot to assassinate former President Bush during a visit to Kuwait. Aspin described the attack as a "wake up call" for Saddam Hussein. Two months later Aspin received a report on the U.S. military performance during the 1991 Gulf War, the result of a study undertaken by the House Armed Services Committee when he chaired it. The report concluded that the U.S. Central Command had greatly exaggerated damage done to Iraqi military equipment, such as tanks and naval vessels, by air strikes. Aspin also had to consider the question of health problems of U.S. service personnel who participated in the action against Iraq. He announced that a preliminary review disclosed no connection between chemical weapon agents and the reported health problems. Nevertheless, he formed a panel of outside experts to examine the issue further.
