Whose strategic thinking defined containment as the core Cold War doctrine?

• A. Henry Kissinger
• B. Dean Acheson
• C. George F. Kennan
• D. Dwight D. Eisenhower

Answer: (C)

The idea being tested is who first defined containment as the guiding strategy for the Cold War. George F. Kennan is the one most closely associated with this framing. As a U.S. diplomat in Moscow, he wrote the Long Telegram in 1946 arguing that the Soviet Union was driven by insecurity and a desire to expand its influence, and that the United States must respond with a long-term, patient policy of containment. This meant using political, economic, and diplomatic tools to limit Soviet expansion and, if necessary, deter aggression, rather than courting direct military confrontation. Kennan’s thinking was later crystallized in his X Article for Foreign Affairs in 1947, which positioned containment as the overarching approach to counter Soviet power. That articulation shaped early Cold War policy, including actions like the Truman Doctrine and the Marshall Plan. While the other figures were influential in different ways—Kissinger with later realpolitik, Acheson with early Cold War decisions, Eisenhower with the New Look and nuclear deterrence—they did not originate the containment framework the way Kennan did.
