George F. Kennan was born in 1904. He was an important historian and an American diplomat who lived in Moscow.
He developed an innovative policy in order to stop Soviet expansion which also meant communism expansion. This policy was called "containment."
Kennan believed that Soviet expansion should be held back without using military forces but instead by controlling some specific crucial territories for the United States. He presumed Stalin had intentions to overthrow western governments.
Furthermore, he claimed that the U.S government should demobilize their troops in Europe.
