I want to know the answer to the following question:
Where did Stalin engage in an aggressive political strategy?
All the background I'm provided with is that "The Soviets had detonated their first nuclear bomb in September 1949; American soldiers had fully withdrawn from Korea; the Americans had not intervened to stop the communist victory in China, and Stalin calculated that the Americans would be even less willing to fight in Korea—which had seemingly much less strategic significance.". Is that enough to answer the question?
