To be brutally honest, neither is correct. Napalm was incindigel with white phosphorus in the mix, difficult to mix at the unit level and outlawed by the Geneva convention. We used a mixture of JP-4 and high phosphate detergent with a white phosphorus fuse element. WWII was the last use of real napalm. (I was in the AF during Vietnam in munitions). Ground forces and many non-munitions types had little idea and continued using the term napalm since it was easier to say and required less explaination than incindigel.
