Lets get something straight, napalm and white phosphorus are NOT 'chemical weapons' and the title of the thread is both misleading and more than a bit partisan. The video, while horrific, is trying to make it appear that the U.S. is dropping something other than WP (White Phosphorus) or Napalm upon the people of Iraq. This, while making a great fairy tale, is false.
For a better definition of what Chemical Weapons are go to:

Napalm
Napalm is a mixture of benzene (21%), gasoline (33%), and polystyrene (46%). Benzene is a normal component of gasoline (about 2%). The gasoline used in napalm is the same leaded or unleaded gas that is used in automobiles.
Red and White Phosphorus
a. At ordinary temperatures, white phosphorus (WP) is a solid which can be handled safely under water. When dry, it burns fiercely in air, producing a dense white smoke. Fragments of melted particles of the burning substance may become embedded in the skin of persons close to a bursting projectile, producing burns which are multiple, deep and variable in size. The fragments continue to burn unless oxygen is excluded by flooding or smothering.
b. WP may be used to produce a hot dense white smoke composed of particles of phosphorus pentoxide which are converted by moist air to droplets of phosphoric acid. The smoke irritates the eyes and nose in moderate concentrations. Field concentrations of the smoke are usually harmless although they may cause temporary irritation to the eyes, nose or throat. The respirator provides adequate protection against white phosphorus smoke.
c. In an artillery projectile white phosphorus is contained in felt wedges which ignite immediately upon exposure to air and fall to the ground. Up to 15% of the white phosphorus remains within the charred wedge and can re-ignite if the felt is crushed and the unburned white phosphorus exposed to the atmosphere.
d. Red phosphorus (RP) is not nearly as reactive as white phosphorus. It reacts slowly with atmospheric moisture and the smoke does not produce thermal injury, hence the smoke is less toxic.
These weapons are classified under the term Incendiary Weapons.
Incendiary agents are used to burn supplies, equipment and structures. The main agents in this group are thermite (TH), magnesium, white phosphorus (WP) and combustible hydrocarbons (including oils and thickened gasoline).
Burns may be produced by flame-throwers, oil incendiary bombs which may also contain phosphorus and sodium, and fire bombs containing thickened gasoline. Lung damage from heat and irritating gases may be a complication added to the injuries from incendiaries, especially in confined spaces.
While it is extremely unpleasant to be on the receiving end of either of these weapon types, neither of them is a Chemical Weapon and any reference to them as such, is totally disingenuous.
P.S.: Just FYI for you partisan types, if you claim I am splitting hairs and you DO consider White Phosphous to BE Chemical Weapons and thus Weapons of Mass Destruction, we can all consider President Bush to have told the 100% unvarnished truth about Iraq having WMD's since, to date, the US and British military have captured thousands of White Phosphorus shells from Iraqi ammo dumps all over Iraq.
