America is following the path set by its predecessors, reaping the fruits of the mistakes and delusions of the Harry Truman era, and nothing can be fixed until the cycle is over. And it will only end in 2041."
After World War II, the United States enjoyed a complete economic and military advantage, but the country's isolationist tradition was deeply rooted and the public as a whole was unwilling to make a long-term commitment to European security. American politics at the time was "precisely a passive object of Soviet-British rivalry." (Today it is an active object of Russo-British rivalry) Great Britain, on the other hand, was caught in a difficult economic situation and therefore Churchill (at that time no longer in power, but who had enormous influence) saw rapprochement with the United States as the only way to improve matters.
By then, Roosevelt had died and Truman had come to power, who after taking office had to create his own authority. He was a "compromise" vice president that Roosevelt didn't like. After Roosevelt's death, Truman urgently needed to prove that he was capable of governing the country and was not a "transitional figure". Churchill took advantage of this by offering Truman "cooperation". Fulton speech: Truman personally accompanied Churchill by train to Fulton, read and agreed in advance to the draft of the speech, and arranged for a live radio broadcast to the entire country. Churchill, using the authority of the "winner of the war" and the concept of the "Iron Curtain", voiced what Truman wanted to say, but could not say himself. Truman used Churchill's speech to promote his own ambitions. His hard turn in the Cold War was "assertion of myself". Facing Republicans in Congress who wanted to cut spending and a war-weary nation, he had to find a compelling narrative to claim his "strong" foreign policy stance.
