Why is cooperation among nations challenging?

• A. Because all nations have identical interests.
• B. Because international law is always enforced.
• C. Due to differing languages, governments, religions, and cultures, as well as the absence of a strong world government.
• D. Because the United Nations has unlimited enforcement power.

Answer: (C)

Cooperation among nations is hard because each country has its own interests, political systems, languages, religions, and cultural norms, and there is no global sovereign with the power to compel all states to act in a single way. International law exists, but enforcement is not automatic or uniform, so compliance depends on negotiations, incentives, and power dynamics. Organizations like the United Nations help coordinate action, but they do not have unlimited enforcement power and rely on member states to carry out decisions. This mix of diverse priorities and the lack of a universal authority makes reaching and sustaining agreements challenging.
