Which alliance was formed to defend member nations against aggression, including the United States, United Kingdom, France, and Canada?

• A. ANZUS
• B. NATO
• C. SEATO
• D. Warsaw Pact

Answer: (B)

Mutual defense among allied nations during the early Cold War is being tested here. NATO was created in 1949 as a mutual defense pact among Western countries, including the United States, United Kingdom, France, and Canada. Its purpose is that an attack on one member is considered an attack on all, providing collective protection against aggression. That stance—ensuring member states defend one another—fits the description precisely and has been central to NATO’s role since its founding. The other options don’t align with this particular coalition. ANZUS includes the United States and two Pacific partners but not the United Kingdom or France. SEATO aimed at containing communism in Southeast Asia, not European security. The Warsaw Pact was a Soviet-led alliance of Eastern Bloc nations, not including Canada or Western powers like the United Kingdom and France.
