The U.S. Uses Illegal Chemical Weapons …
Both the New York Times and Washington Post confirm that the U.S. used white phosphorous in densely populated Iraq and Syria.
Why does this matter?
The use of white phosphorus is a war crime under international treaties and domestic U.S. laws. For example, the Battle Book, published by the U.S. Command and General Staff College at Fort Leavenworth, Kansas, contains the following sentence:
It is against the law of land warfare to employ WP [i.e. white phosphorous] against personnel targets.
