Gulf War Illness and the Khamisiyah Cover-Up Claims
Many veterans of the 1990-91 Gulf War came home with chronic, unexplained symptoms. The Pentagon and CIA long said no U.S. troops had been exposed to chemical weapons; in June 1996 the Defense Department acknowledged that U.S. troops had destroyed Iraqi chemical munitions at Khamisiyah. Later estimates put about 100,000 troops in the potential exposure zone, though the GAO said those estimates could not be adequately supported.

The Story
The 1991 Gulf War was a fast, lopsided victory. The illnesses came afterward.
Many of the roughly 700,000 U.S. troops who served came home with problems that routine tests couldn't explain. A federal research committee later described the typical pattern as 'a combination of memory and concentration problems, persistent headache, unexplained fatigue, and widespread pain,' sometimes with digestive problems, breathing symptoms and skin rashes. Veterans wanted to know what they had been exposed to. Among the suspects were the anti-nerve-gas pills they had taken, pesticides, oil well smoke and Iraqi chemical weapons.
GAO: the 'no exposure' conclusion 'was maintained until June 1996.'
On chemical weapons, the official answer was no. The Government Accountability Office reports that when the question came up in summer 1993, the Defense Department and the CIA concluded that no troops had been exposed, because there were no forward-deployed chemical munitions and any plumes from bombed facilities could not have reached the troops.
That answer had a problem, and its name was Khamisiyah. In March 1991, after the fighting ended, U.S. troops blew up munitions at this huge Iraqi depot, which had nearly 100 storage bunkers. In October 1991, UN inspectors found evidence there of rockets 'filled with a combination of sarin and cyclosarin nerve agents.' But, GAO says, the 'no exposure' conclusion 'was maintained until June 1996, when DOD publicly acknowledged that U.S. troops had destroyed stockpiles of chemical munitions at Khamisiyah after the war.'
Then the numbers started climbing. In June 1996 DOD estimated that 300 to 400 troops had taken part in the demolition. By September it was 5,000 within 25 kilometers, and by October 20,000 within 50. Computer plume modeling in July 1997 put the number at 98,910, and in 2000 at 101,752.
Congress was not impressed. A 1997 House committee report was titled 'Gulf War Veterans' Illnesses: VA, DOD Continue to Resist Strong Evidence Linking Toxic Causes to Chronic Health Effects.' In 2004 GAO examined the plume modeling and concluded that DOD's conclusions about exposure 'cannot be adequately supported.' The plume heights and hazard areas had been underestimated, and different models disagreed widely. The CIA did not concur with GAO's report, saying it did not have enough time to review the draft.
In 2008 the congressionally mandated Research Advisory Committee on Gulf War Veterans' Illnesses issued a major report. It found that the illness 'affects at least one fourth of the 697,000 U.S. veterans' of the war, and that it is not the result of combat stress. It named two exposures consistently linked to it: the anti-nerve-gas drug pyridostigmine bromide and heavy use of pesticides. Low-level nerve agent exposure, it said, could not be ruled out. The committee wrote that the veterans' health problems had been 'for too long, denied or trivialized.'
So, the verdict: the illness is real, according to the federal committee, and the early official denial of chemical exposure was wrong. What caused the illness, and how many troops were actually exposed at Khamisiyah, is still disputed.
Origins
According to the Government Accountability Office, when possible low-level chemical exposure first became an issue in summer 1993, the Defense Department and the CIA concluded that no troops had been exposed. 'This conclusion was maintained until June 1996, when DOD publicly acknowledged that U.S. troops had destroyed stockpiles of chemical munitions at Khamisiyah after the war.'
The Claims
- Gulf War veterans suffer from a real illness caused by wartime exposures.
- Troops were exposed to nerve agents, and officials played it down or covered it up.
Key Evidence
- GAO reports that U.S. troops carried out 'large-scale demolition operations' at Khamisiyah in March 1991, and that rockets there 'were found to have been filled with a combination of sarin and cyclosarin nerve agents.'
- DOD's estimate of potentially exposed troops grew from 300 to 400 (June 1996) to 5,000, then 20,000, then 98,910 (July 1997), then 101,752 (2000), according to GAO. In 2004 GAO concluded that DOD's exposure conclusions 'cannot be adequately supported.'
- In 2008 the congressionally mandated Research Advisory Committee on Gulf War Veterans' Illnesses concluded that Gulf War illness 'affects at least one fourth of the 697,000 U.S. veterans' of the war.
The Evidence Against
- The cause is still debated. The 2008 committee linked the illness most consistently to two exposures, pyridostigmine bromide anti-nerve-gas pills and pesticides. It said a link to low-level nerve agent exposure could not be ruled out, which is weaker than a finding of cause.
- Official denials before 1996 were wrong, but the records used here show shifting estimates and flawed modeling, not proof of a deliberate plot to make troops sick.
- The CIA did not concur with GAO's 2004 report, saying it could not finish reviewing the draft in the time allowed. DOD agreed to do no more plume modeling but rejected GAO's other recommendation.
