Adjective[edit] belligerent â(comparative more belligerent, superlative most belligerent) 1  Engaged in warfare, warring. 2  Eager to go to war, warlike. 3  Of or pertaining to war. ( 4 By extension) Aggressively hostile, eager to fight.  Acting violently towards others.
The rules of warfare are not suspended, however, or otherwise rendered inapplicable merely because the grounds for fighting a particular war are unlawful. In an illegal war both the aggressor and other belligerents must still comport their behavior with the international customs, practices, and conventions of war. At the same time, some authority suggests that one belligerent may disregard certain rules of war in reprisal for its enemy's disregard of the same rules.
