Being on warpath is a phrase used to describe someone who is agitated, angry, and ready to confront an adversary. However, there are several antonyms that can be used to describe the opposite state of being. One suitable antonym is peacekeeping, which means to promote peace and resolve conflicts without violence. Another antonym is diplomacy, which involves negotiations and compromise to settle disputes. A third antonym is conciliatory, which involves making amends and seeking reconciliation. Being calm and peaceful can help avoid the escalation of conflicts, leading to a more harmonious and cooperative relationship between individuals or groups.
