This issue involves complex ethical and legal considerations, and countries usually follow international law as well as their own legal and moral standards when dealing with military decisions related to this issue. First, under international humanitarian law, especially the Geneva Conventions, countries have an obligation to protect civilians and non-combatants in armed conflicts. Any military action should follow the principles of distinction (distinguishing between combatants and civilians), proportionality (the use of force should be proportionate to the military objective) and necessity (military action should be necessary to achieve legitimate military objectives). The concept of sacrificing a few innocent people to achieve a greater victory is often seen in ethics as a manifestation of utilitarianism, that is, the view that choices are justified as long as the outcome maximizes the overall benefit. However, many people would oppose this view because it may mean an infringement of individual rights and a deviation from the principle of humanity. Ultimately, the decision lies in the hands of decision-makers, who must balance military objectives with moral obligations and consider the legal consequences of the decision and the impact on international relations. This is a decision that requires careful consideration and responsibility, and should not be made lightly.
