Answer: The president who most radically dealt with communism and expanded US influence after World War II.
Step-by-step explanation:
Truman began purging Communist sympathizers in his ranks. All those who sympathized with this political system had no place in his government. Due to corruption and support for communism, some 200 people in the US administration have lost their jobs. At a global level, that is, foreign policy, Truman expressed his dislike for this political system.
In 1947, he signed the National Security Act, thus creating individual branches for the security of countries that were independent of the military (such as the CIA ). He worked intensively to strengthen US influence after the war. Supported the Marshall Plan for the Reconstruction of Europe, encouraged the formation of Israel, all to enhance the foreign policy and position of the United States.
