International organizations (defense pacts): Which was the first country to withdraw from CENTO (formerly the Baghdad Pact)? Consider original signatories: Iraq, Iran, Pakistan, Turkey, and the United Kingdom. Choose the correct country that exited first.

Given data

• CENTO (Central Treaty Organization) evolved from the Baghdad Pact.
• Ask: Which member left first?

Concept/Approach
After the 1958 revolution in Iraq, the country withdrew in 1959 from the Baghdad Pact, precipitating the rebranding to CENTO. Later exits (e.g., Iran in 1979) led to dissolution, but Iraq's withdrawal was first.

Common pitfalls
Confusing the late-1970s withdrawals (e.g., Iran) with the first exit.

Final Answer
Iraq
