Practice Relating to Rule 84. The Protection of Civilians and Civilian Objects from the Effects of Incendiary Weapons
In 2010, in its objection to the reservation by the United States of America to the 1980 Protocol III to the Convention on Certain Conventional Weapons, Ireland stated:
The Government of Ireland has examined the reservation made on 21 January 2009 by the United States of America to Article 2, paragraphs 2 and 3 of Protocol III to the Convention on Prohibitions or Restrictions on the Use of Certain Conventional Weapons which may be deemed to be Excessively Injurious or to have Indiscriminate Effects upon notification of its consent to be bound thereby [in which the United States of America reserves the right to use incendiary weapons against military objectives located in concentrations of civilians where it is judged that such use would cause fewer casualties and/or less collateral damage than alternative weapons, but in so doing will take all feasible precautions with a view to limiting the incendiary effects to the military objective and to avoiding, and in any event to minimizing, incidental loss of civilian life, injury to civilians and damage to civilian objects].
The provisions to which the aforesaid reservation refers prohibit, with one exception, the use of incendiary weapons against military objectives located within concentrations of civilians. The Government of Ireland regards the reservation made by the United States of America as invalid, inasmuch as it is incompatible with the object and purpose of Protocol III.
The Government of Ireland therefore objects to the aforesaid reservation made by the United States of America.
This objection shall not preclude the entry into force of Protocol III between Ireland and the United States of America.
