Declaration made upon ratification:
"(1) It is the understanding of the United States of America that "special protection", as defined in Chapter II of the Convention, codifies customary international law in that it, first, prohibits the use of any cultural property to shield any legitimate military targets from attack and, second, allows all property to be attacked using any lawful and proportionate means, if required by military necessity and notwithstanding possible collateral damage to such property.
(2) It is the understanding of the United States of America that any decision by any military commander, military personnel, or any other person responsible for planning, authorizing, or executing military action or other activities covered by this Convention shall only be judged on the basis of that person's assessment of the information reasonably available to the person at the time the person planned, authorized, or executed the action under review, and shall not be judged on the basis of information that comes to light after the action under review was taken.
(3) It is the understanding of the United States of America that the rules established by the Convention apply only to conventional weapons, and are without prejudice to the rules of international law governing other types of weapons, including nuclear weapons.
(4) It is the understanding of the United States of America that, as is true for all civilian objects, the primary responsibility for the protection of cultural objects rests with the Party controlling that property, to ensure that it is properly identified and that it is not used for unlawful purposes."
