Philip Jones Griffiths describes its use in Vietnam:
“ NAPALM. The most effective anti-personnel weapon, it is euphemistically described as “unfamiliar cooking fluid” by those in favor of American military methods–Attributing all napalm cases to domestic accidents caused by the people using gasoline instead of kerosene in their cooking stoves. Kerosene is far too expensive for the peasants, who normally use charcoal for cooking. The only “cooking fluid” they know is very “unfamiliar” – it is delivered through their roofs by U.S. planes.

Some of its finer selling points were explained to me by a pilot in 1966: “We sure are pleased with those backroom boys at Dow. The original product wasn’t so hot – if the gooks were quick they could scrape it off. So the boys started adding polystyrene – now it sticks like shit to a blanket. But then if the gooks jumped under water it stopped burning, so they started adding Willie Peter (WP – white phosphorus) so’s to make it burn better. It’ll even burn under water now. And just one drop is enough, it’ll keep on burning right down to the bone so they die anyway from phosphorous poisoning.”[4]

“Napalm is the most terrible pain you can imagine,” said Kim Phuc, a napalm bombing survivor known from a famous Vietnam War photograph. “Water boils at 100 degrees Celsius. Napalm generates temperatures of 800 to 1,200 degrees Celsius.”[5]

When the Americans dropped the atom bomb, they were so pleased with themselves.

They spent the next 55 years meddling in world politics and building bigger nukes.
What did they think would happen?
Sooner or later, someone would reciprocate.
I saw a documentary/film once in which Chinese schoolchildren quizzed an American schoolteacher regarding Hiroshima. The American seemed quite surprised that the Chinese children would be upset about the tragedy in Japan.
