I want to know the answer to the following question:
Why did Kim Il-Sung redeploy his military troops?
All the background I'm provided with is that "On 18 September, Stalin dispatched General H. M. Zakharov to Korea to advise Kim Il-sung to halt his offensive around the Pusan perimeter and to redeploy his forces to defend Seoul.". Is that enough to answer the question?
Answer: yes
