Which term best fits a formal agreement among nations to support one another in times of need?

• A. Treaties
• B. Alliances
• C. Pacts
• D. Confederations

Answer: (B)

Mutual defense and ongoing cooperation among nations is the hallmark of an alliance. When countries form an alliance, they commit to supporting each other in times of need, often including military aid, strategic coordination, and diplomatic backing. That emphasis on a standing, collaborative pact tailored to security best captures the idea described in the prompt.

Treaties are formal agreements between states and can cover a wide range of topics, not exclusively mutual defense or ongoing obligation. Pacts also denote formal agreements but can be more general or less institutionalized in everyday usage. Confederations describe a loose union of states where sovereignty remains with the member states and a centralized authority is limited, which isn’t typically the arrangement meant by a formal defense-oriented agreement. In this context, the term that best conveys a formal, ongoing commitment to assist one another in times of need is alliance.
