CCW 隻是禁止對 civilian population 使用燃燒彈

International law[edit]

International law does not specifically prohibit the use of napalm or other incendiaries against military targets,^[31] but use against civilian populations was banned by the United Nations Convention on Certain Conventional Weapons (CCW) in 1980.^[32] Protocol III of the CCW restricts the use of all incendiary weapons, but a number of countries have not acceded to all of the protocols of the CCW. According to the Stockholm International Peace Research Institute (SIPRI), countries are considered a party to the convention, which entered into force as international law in December 1983, as long as they ratify at least two of the five protocols. Approximately 25 years after the General Assembly adopted it, the United States signed it on January 21, 2009, President Barack Obama's first full day in office.^[33][34] Its ratification, however, is subject to a reservation that says that the treaty can be ignored if it would save civilian lives.^[34]

 

Multiple nations (including the United States, China, Russia, Iran and North Korea) maintain large stockpiles of napalm-based weapons of various types.
