Answer:
Stephen Ambrose believed that Truman's speech was the real reason for the Cold War because of its content. It was almost a war declaration.
Step-by-step explanation:
The Truman Doctrine is the name given to a foreign policy implemented during the Truman government and aimed at the block of capitalist countries in the pre-Cold War period. Such a doctrine was intended to prevent the spread of socialism, especially in capitalist nations considered fragile. However, according to Stephen Ambrose, some points of Truman's speech can be interpreted as a war declaration, especially when he talks about oppression and the subjugate countries under the Communis power.
