Here is the relevant data from your link, I suppose it could be spun to say that the US poisoned the water, but I would say that Saddam did the posioning, not the US.
IRAQ HAD NOT
COMPLETED THE MAJOR PURCHASE AND DELIVERY OF SPARE MEMBRANES
BEFORE INVADING KUWAIT. ATTEMPTS TO PROCURE MEMBRANES SINCE
THE UN SANCTIONS WERE IMPOSED HAVE FAILED. SINCE THE ATTEMPT
TO IMPORT MEMBRANES CORRESPONED TO THEIR NORMAL REPLACEMENT PERIOD, IRAQ
APPARENTLY DID NOT STOCKPILE ABUNDANT SPACE MEMBRANES OR CHEMICALS AND
PROBABLY HAD NO MORE THAN A 2-MONTH SUPPLY PRIOR TO THE INVASION.
The relevant Fact being do not ****ing invade your neighbors, and if you do, make sure you are prepared.
