Napalm or napalm-like incendiary weapons are not outlawed.
International law permits their use against military forces.

Incendiary devices like white phosphorous were banned by the Geneva
Convention.
The U.S. did not sign the relevant protocol to the convention.

The use of white phosphorus or fuel air explosives are not prohibited or
restricted by Protocol II: http://www.nawcwpns.navy.mil/~treaty/CCWC.html

What is restricted is the purposeful and malicious targeting or making
civilian populations the object of attack by incendiary weapons and
restricts the use of incendiary weapons against military targets located
within a concentration of civilians, and from what evidences are given and
shown, there is little to no evidence given to conclusively indicate or
prove that the US did in fact purposely and maliciously target civilians for
attack with white phosphorous or other incendiary weaponry or devices in or
within Fallujah.

What appears to be white phosphorous in the Italian Neo-Kommie propaganda
video has not been substantiated by any type of forensic evidence
whatsoever.

Probably will not be long before reports start circulating that the US
somehow used Agent Orange in Fallujah and parts of Iraq, as well.
