From the BBC:
There is evidence linking chronic health problems suffered by Gulf War veterans to exposure to pesticides and nerve agents, US research has found. ...
These were an anti-nerve gas agent given to troops, pesticides used to control sand-flies, and the nerve-gas sarin that troops may have been exposed to during the demolition of a weapons depot.
"Convergent evidence now strongly links a class of chemicals - acetyl cholinesterase inhibitors - to illness in Gulf War veterans," Dr [Beatrice] Golomb [the committee's chief scientist] told Reuters. [Published in my favorite journal: PNAS, but no link yet.]
The real kicker is, of course, "unlike the most recent conflict in Iraq, the ground conflict during the 1991 Gulf War lasted only a few days, she added." And in those few days, one third, one third, of the soldiers acquired lifelong conditions.
George's Folly has lasted how long now?
