Practice Relating to Rule 14. Proportionality in Attack
Section B. Determination of the anticipated military advantage
Upon signature of the 1998 ICC Statute, Egypt declared:
The term “the concrete and direct overall military advantage anticipated” used in article 8, paragraph 2 (b) (iv), must be interpreted in the light of the relevant provisions of [the 1977 Additional Protocol I]. The term must also be interpreted as referring to the advantage anticipated by the perpetrator at the time when the crime was committed. No justification may be adduced for the nature of any crime which may cause incidental damage in violation of the law applicable in armed conflicts. The overall military advantage must not be used as a basis on which to justify the ultimate goal of the war or any other strategic goals. The advantage anticipated must be proportionate to the damage inflicted.
