In his Iron Curtain speech, former British Prime Minister Winston Churchill affirmed the following two things:
1. His wish to side with the United States against the Soviet Union: Churchill emphasized the need for the Western democracies, particularly the United States and Britain, to stand together against the expansionist policies of the Soviet Union in Europe.
2. His belief that only the United States possessed nuclear weapons: During the speech, Churchill highlighted the United States' possession of nuclear weapons as a significant factor influencing the global balance of power.
These two points were key aspects of Churchill's message in the Iron Curtain speech, which aimed to address the growing tensions and ideological divide between the Western powers and the Soviet Union in the aftermath of World War II.
