Which of the following statements is NOT a principle of the law of armed conflict?

The correct answer highlights a key misunderstanding of the principles of the law of armed conflict. In this context, the principle states that how military objectives are achieved must be in accordance with established ethical and legal standards, including considerations of military necessity and humanity. This means that even if there is a reasonable chance of a mission's success, the means employed to achieve that goal must still conform to the principles of distinction, proportionality, and humanitarian treatment.

The statements that represent the principles of the law of armed conflict emphasize the importance of protecting those who are not participating in hostilities, ensuring that the use of force is proportional to the military advantage anticipated, and distinguishing between combatants and non-combatants. These principles reinforce the obligation to conduct military operations in a manner that minimizes harm to civilians and non-combatants, aligning with international humanitarian law's core tenets. Thus, the selected answer correctly identifies a statement that contradicts these foundational principles.
