Practice Relating to Rule 14. Proportionality in Attack
The Report on the Practice of Kuwait affirms that numerous statements by Kuwait highlight the importance of the principle of proportionality in attack. 
Report on the Practice of Kuwait, 1997, Chapter 1.5.
The report specifies that there is an obvious violation of the principle of proportionality if no military advantage could be expected from the destruction of an object. This point was illustrated by the country’s vigorous protests over violations of the principle of proportionality committed by the Iraqi armed forces in setting oil wells and other facilities on fire without any hope of gaining a military advantage. The report notes that it is the opinio juris of Kuwait that the principle of proportionality must be respected, and that objects whose destruction provide no military advantage should be spared.
