Napalm Survivor Tells of Healing After Vietnam War
University of Connecticut Advance. but use against civilian populations was banned by the UN Convention on Certain Conventional Weapons (CCW) in 1980. Protocol on Incendiary Weapons, 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, it was reported that the US signed it on 21 January 2009, President Barack Obama's first full day in office.
Its ratification, however, is subject to a reservation that says that the treaty can be ignored if it would save civilian lives.
[ The UN has also acknowledged that the US had ratified the CCW in March 1995, 13 years after the country became a signatory to it.]
