Military, political, and diplomatic leader of Vietnam who received the Nobel Peace Prize in 1973 for negotiating the withdrawal of US troops from Vietnam; born Phan Dinh Khai.

• A. Ho Chi Minh
• B. Vo Nguyen Giap
• C. Le Duc Tho
• D. Pham Van Dong

Answer: (C)

Le Duc Tho, born Phan Dinh Khai, was a Vietnamese military, political, and diplomatic leader who helped negotiate the Paris Peace Talks that led to the withdrawal of U.S. troops from Vietnam. He and U.S. Secretary of State Henry Kissinger were awarded the Nobel Peace Prize in 1973 for those negotiations, though Tho declined the prize. This link to the specific diplomacy and his prominent leadership role in Vietnam makes him the best match. Ho Chi Minh was the revolutionary founder who died before the prize; Vo Nguyen Giap was the renowned general; Pham Van Dong was a senior official, but none of them are the diplomat primarily honored for ending U.S. involvement in Vietnam with the Nobel Prize in 1973.
