What is the term for the collaborative arena between states that aids in nonviolent conflict resolution?

The term that best refers to the collaborative arena between states that aids in nonviolent conflict resolution is "Society of States." This concept emphasizes the interactions and relationships among sovereign states, where diplomacy, cooperation, and negotiation are prominent methods used to resolve disputes peacefully.

The Society of States is grounded in the idea that states can come together in a system where they engage with one another to address conflicts, establish norms, and maintain stability in the international system. This framework aligns well with theories in international relations that advocate for multilateralism and the importance of dialogue in preventing violence and fostering cooperation.

The other options, while related to concepts of international collaboration, do not specifically encapsulate the process of nonviolent conflict resolution as effectively as the Society of States. The term "International Community," for instance, broadly refers to all states and non-state actors with shared interests, which may not focus solely on conflict resolution. "Global Governance" typically addresses larger frameworks for addressing global issues, including but not limited to conflict, while "Nations Coalition" suggests a more structured grouping that may imply certain military or strategic alliances, rather than solely a forum for peaceful negotiation.
