snip: The Law of War Manual:
* Declares legitimate the use of nuclear weapons, stating, “There is no general prohibition in treaty or customary international law on the use of nuclear weapons.” Nor is the use of nuclear weapons considered “inherently disproportionate,” even if the target is a military force that does not possess nuclear weapons.
* Authorizes the use of incendiary weapons such as napalm, herbicides (such as Agent Orange in Vietnam), laser weapons and riot control agents (tear gas, pepper spray, etc.), as well as depleted uranium munitions.
* Authorizes cluster munitions, mines and booby-traps, noting that “the United States is not a Party to the Convention on Cluster Munitions.”
* Authorizes the use of exploding (hollow-point) bullets, stating that the United States government was not a party to the 1868 St. Petersburg declaration banning their use or the 1899 Declaration on Expanding Bullets.
