Kos has dug up some interesting information on the White Phosphorus debate. In particular this Pentagon intelligence document describing the alleged use of WP as a chemical weapon on the Kurds.

PRESIDENT SADDAM ((HUSSEIN)) MAY HAVE POSSIBLY USED WHITE
PHOSPHOROUS (WP) CHEMICAL WEAPONS AGAINST KURDISH REBELS AND THE
POPULACE IN ERBIL (GEOCOORD:3412N/04401E) (VICINITY OF IRANIAN
BORDER) AND DOHUK (GEOCOORD:3652N/04301E) (VICINITY OF IRAQI
BORDER) PROVINCES, IRAQ. THE WP CHEMICAL WAS DELIVERED BY
ARTILLERY ROUNDS AND HELICOPTER GUNSHIPS (NO FURTHER INFORMATION
AT THIS TIME). APPARENTLY, THIS TIME IRAQ DID NOT USE NERVE GAS AS
THEY DID IN 1988, IN HALABJA (GEOCOORD:3511N/04559E), IRAQ,
BECAUSE THEY WERE AFRAID OF POSSIBLE RETALIATION FROM THE UNITED STATES
(U.S.) LED COALITION. THESE REPORTS OF POSSIBLE WP CHEMICAL WEAPON
ATTACKS SPREAD QUICKLY AMONG THE KURDISH POPULACE IN ERBIL AND
DOHUK. AS A RESULT, HUNDREDS OF THOUSANDS OF KURDS FLED FROM THESE
TWO AREAS AND CROSSED THE IRAQI BORDER INTO TURKEY.

That seems pretty conclusive. The Pentagon considered WP a chemical weapon when Saddam used it, but now we're accused of using it on civilians and it suddenly is no longer a chemical weapon.

What's also strange is that it's like there's some rule that if you are in control of Iraq you must torture and use chemical weapons on the people. They must be asking for it, wearing those sexy chemical weapons suits and pretending they have a high threshold for pain.
