Evaluate the impact of the Truman Doctrine and the Marshall Plan on the development of the Cold War. The Truman Doctrine and the Marshall Plan had a great impact on the Cold War in its early years; this is the reason for the development of the Cold War. This is the reason for the spark between the ideologies of the two superpowers. This showed both superpowers the threat facing them and the importance of expansion, because without expansion, countries will eventually be diminished by the opposing superpower. The early years of the Cold War marked the beginning of the conflict between the two most powerful countries, namely the United States and the USSR. This made a gentle solution to Stalin and Truman's mutual dislikes impossible, because the two powers could no longer compromise. The various reasons that started the Cold War were the refusal of Marshall Aid, the policy of containment and the clash of ideologies. The first thing that shook up the Cold War was the Soviets' refusal to accept Marshall Aid, because they thought it was a bad thing. an attempt to make Europe dependent on the capitalist countries and in this way the capitalist countries can expand their empire.

This geographical divide between the two...... middle of paper......so that they obtain the necessary security. The United States also attempted to expand, but in a much more covert way, through the Marshall Plan the Western European states became more dependent on the United States, which gave Truman immeasurable power to the foreigner. Both Stalin and Truman viewed opposing expansionism as aggressive action and their animosity became more determined. The Truman Doctrine and the Marshall Plan played a large role in the subsequent development of the Cold War; it was one of the most important. The clash of ideologies and what it entailed were at least as important. Overall, the Truman Doctrine and the Marshall Plan sparked the conflict between the United States and the USSR. Its importance in the development of the Cold War was rivaled only by the ideological clash between the two states. This leads them from simple distrust that evolved into hatred and hatred..
