What was Joseph Stalin's reaction to the defeat of Japan in World War 2?

Joseph Stalin viewed the defeat of Japan in World War II as a significant opportunity to expand Soviet influence in Asia. Following Japan's surrender, he sought to establish a stronger presence in the region, particularly by entering the war against Japan shortly before the surrender and occupying territories in Manchuria and the Kuril Islands. This move aligned with his broader strategy of spreading communism and securing Soviet borders. Stalin's actions contributed to the post-war geopolitical landscape in Asia, setting the stage for future tensions during the Cold War.
