Final answer:
Enemy military aircraft should not be attacked in neutral airspace or when they are out of combat, according to the Law of Armed Conflict, to protect civilians and prevent conflict escalation.
Step-by-step explanation:
According to the Law of Armed Conflict (LOAC), enemy military aircraft should not be attacked or destroyed in certain protected spaces. The sanctity of neutral airspace must be respected, meaning military aircraft of warring parties cannot be attacked when they are within the airspace of a nation that is not involved in the conflict. Another situation where attacks are prohibited is when an aircraft is recognized as being out of combat, for instance, if it is displaying signs of surrender or incapacity to fight due to technical issues. These regulations aim to protect civilians and prevent escalations in hostilities that could arise from violating neutral spaces or targeting those who are no longer part of the combat operations.
