Rules of War
Neutral Countries
All military forces are similarly bound by the rules of war with regard to neutral countries. By definition a neutral country is not a party to a military conflict between belligerent states. Unless bound by a treaty, governments are not required to remain neutral in a war, but they are presumed to be neutral unless they manifest adherence to one side or the other by word or act. Neutral countries must neither help nor harm a belligerent state nor allow a belligerent to make use of their territory or resources for military purposes. Instead, neutral states must assume a position of strict impartiality.
Neutral territory is considered an ASYLUM for prisoners of war, who become free upon reaching neutral ground. Belligerent troops may enter neutral territory to avoid capture but may be rejected or disarmed by the host country. Belligerent aircraft are not permitted to enter neutral airspace, and if they land, the host country may intern them. Belligerent warships may be granted asylum when they are in distress or in need of repairs. If belligerents abuse this privilege, however, asylum may be revoked, and their forces may be ordered to leave.
