Final answer:
The claim that the collapse of the Soviet Union was attributed to President Truman's signing of the G.I. Bill in 1947 is not supported by historical evidence. The collapse of the Soviet Union in 1991 was influenced by a range of factors and cannot be solely attributed to one event or policy.
Step-by-step explanation:
The dominant claim of the statement that the collapse of the Soviet Union can be attributed to President Truman's signing of the G.I. Bill in 1947 is not supported by historical evidence.
The G.I. Bill, also known as the Servicemen's Readjustment Act, provided benefits to servicemen returning from World War II, such as funds for college tuition, home loans, and unemployment benefits. While the G.I. Bill did contribute to the growth of the middle class and the expansion of access to education, it cannot be solely attributed to the collapse of the Soviet Union.
The collapse of the Soviet Union in 1991 was a complex event influenced by a range of factors, including economic issues, political reforms, and internal tensions within the Soviet Union. It is important to consider multiple factors and historical context when analyzing significant historical events like the collapse of the Soviet Union.
