Overall verdict
Israel illegally used white phosphorus in Gaza and Lebanon.
A recurring allegation from HRW, Amnesty, social media, and press coverage concerning Israeli use of white phosphorus munitions.
The claim that Israel's use of white phosphorus is illegal per se is legally inaccurate. White phosphorus is not banned in all circumstances under international law. The legal question depends on munition type, purpose, location, civilian concentration, precautions, feasible alternatives, and whether use violates incendiary-weapons or targeting rules in a specific incident. Allegations about Gaza and Lebanon must be separated by date and location. Evidence may support incident-specific criticism or investigation, but the categorical claim that any Israeli white-phosphorus use is automatically illegal overstates the law.
White-phosphorus claims are visually powerful and often collapse weapon use, risk to civilians, and illegality into one step.

weapon_identification_to_illegality_claim
Track munition identification, target/location, civilian proximity, purpose, and applicable treaty/customary rule.
White phosphorus is not automatically illegal under international law. The legal question is incident-specific: munition, purpose, location, civilians, precautions and alternatives. Blanket 'Israel used WP, therefore illegal' is legally inaccurate.
