You say Potato I say....

Looks like when we use White Phosphorous it is NOT a chemical weapon but when Saddam used White Phosphorous it WAS a chemical weapon.

Think Progress reports a 1995 Pentagon document that discloses....

IRAQ HAS POSSIBLY EMPLOYED PHOSPHOROUS CHEMICAL WEAPONS AGAINST THE KURDISH POPULATION IN AREAS ALONG THE IRAQI-TURKISH-IRANIAN BORDERS. […]

IN LATE FEBRUARY 1991, FOLLOWING THE COALITION FORCES’ OVERWHELMING VICTORY OVER IRAQ, KURDISH REBELS STEPPED UP THEIR STRUGGLE AGAINST IRAQI FORCES IN NORTHERN IRAQ. DURING THE BRUTAL CRACKDOWN THAT FOLLOWED THE KURDISH UPRISING, IRAQI FORCES LOYAL TO 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.

How many times have you heard Saddam used chemical weapons on his own people (Kurds) as a justification for war. What does it mean if we have done it?
