The purpose of international treaties in politics is to formalize agreements between nations, establishing rules and expectations governing their interactions. These treaties play a key role in addressing global challenges such as trade, security, and environmental concerns. By promoting cooperation, treaties facilitate peaceful relations and enhance mutual understanding among countries. They also create mechanisms for dispute resolution and compliance, promoting international stability and legal frameworks. Ultimately, international treaties reflect a commitment to collaboration and consensus-building, essential for navigating the complexities of an interconnected world.
