When discussing international conflicts and wars, the term "war nations" commonly refers to countries that are involved in armed conflicts. However, there are alternative phrases that can be used to describe these nations and their involvement in war. "Belligerent states" or "combatant countries" are terms that can be used to reference countries that are actively engaged in warfare. "Opposing factions" or "warring parties" may be used to describe the different sides involved in a conflict. Finally, "military powers" or "belligerent nations" are terms that may be employed to describe countries with large military capabilities that often engage in international conflicts.
