Napalm

The Pentagon admits that US troops used firebombs--incendiary bombs made with kerosene jet fuel--on troops in Iraq. Considered inhumane by many human rights groups (but remaining legal under international law), firebombs are familiarly referred to as napalm, due to effects on the human body that are "remarkably similar" to the controversial benzene-and-gasoline bombs of Vietnam. Col. James Alles said, "The generals love napalm. It has a big psychological effect."
