45. Which of the following is a power officially granted to the United Nations?

Answer: C

Explanation:

Legitimizing international response against aggressor nations

The United Nations is officially granted the power to legitimize international responses against aggressor nations, which is crucial for maintaining global peace and security.

A) Approving the constitutions of newly formed governments

This option is incorrect as the United Nations does not have the authority to approve the constitutions of newly formed governments. While the UN may assist in guiding nations during their formation or transition, the ultimate decision-making power lies with the nations themselves and their citizens.

B) Regulating trade among nation-states

Regulating trade among nation-states is not a power granted to the United Nations. Trade regulations are typically managed by individual nations or through agreements between them, such as those facilitated by the World Trade Organization (WTO), rather than by the UN.

C) Legitimizing international response against aggressor nations

This is the correct answer as the United Nations has the authority to endorse and legitimize collective action, including military intervention, to respond to acts of aggression. This power is primarily exercised through the UN Security Council, which can determine threats to peace and security.

D) Controlling international migration

Controlling international migration is not a power granted to the United Nations. While the UN addresses migration issues, it does so primarily through cooperation and guidance rather than direct control over migration policies, which remain the prerogative of individual countries.

Conclusion

The United Nations' ability to legitimize international responses against aggressor nations is a fundamental aspect of its mission to promote peace and security globally. Other options, such as approving constitutions or regulating trade, do not fall within the UN's scope of authority, demonstrating the specificity and significance of the correct answer.
