We already discussed this in the political forum. They aren't chemical weapons they are incendiary weapons, and they break no laws as the US has never ratified a treaty with respect to their usage. Furthermore, the treaty only bans their use with respect to civilians, not enemy combatants. I forsee a snowballing political thread in here..
Discussion should be taken to this thread that already exists:

In fact watch the vid at the bottom of this very page by Peter Kaiser, Organisation for the Prohibition of Chemical Weapons... He tells you they aren't chemical they are incendiary.
