Which of the following is a purpose of international treaties?

The correct choice highlights a fundamental role of international treaties: establishing agreements between countries on various issues. Treaties serve as formal and legally binding agreements that facilitate cooperation and dialogue on matters such as trade, defense, environmental protection, human rights, and more. They provide a structured framework through which nations can negotiate resolutions to disputes, collaborate on shared challenges, and establish common goals. Such agreements are essential for fostering stability, ensuring mutual respect among nations, and promoting diplomacy.

The other options do not accurately reflect the primary function of international treaties. For instance, creating national laws pertains to domestic legislation rather than international agreements, while regulating domestic political parties is specifically related to internal governance structures within a state. Managing local community rights is also more concerned with local or regional governance than with the international agreements that treaties represent. Hence, the essence of treaties is truly captured in their role as mechanisms for international cooperation and agreement.
