Final answer:
The Truman Doctrine was supposed to keep more countries democratic by providing economic aid to counteract the spread of communism and support governments under threat.
Step-by-step explanation:
The Truman Doctrine was designed to keep more countries democratic by providing economic aid, specifically to prevent the spread of communism by supporting governments that were threatened by communist uprisings or external pressures. When Britain could no longer afford to support the governments of Greece and Turkey against communist forces, the U.S. under President Truman stepped in. On March 12, 1947, Truman asked Congress for $400 million in aid to help the Greek government defeat communist rebels and assist Turkey in maintaining control of key strategic points. This doctrine supported the U.S. foreign policy strategy of containment, aimed at limiting the expansion of communism.In summary, the Truman Doctrine intended to maintain democratic governments and counteract the influence of the Soviet Union during the early Cold War period. This was primarily achieved by offering military assistance, including financial support, weaponry, and training, to help these nations resist communist takeovers, as reflected in the outcomes for Greece and Turkey.
