Why did Stalin approve the North's invasion of the South?

Stalin approved North Korea's invasion of South Korea in 1950 as part of his broader strategy to expand communist influence in Asia. He viewed the conflict as an opportunity to challenge U.S. power in the region and solidify the Soviet Union's position during the Cold War. Additionally, he believed that a successful invasion could inspire communist movements elsewhere, aligning with his goal of promoting global communism. Stalin's support provided the North with military and logistical aid, further emboldening Kim Il-sung's ambitions for unification.
