I want to know the answer to the following question:
Who believes that the North Koreans only appeared to fail to effective execute their withdrawal plan?
All the background I'm provided with is that "Historian Bruce Cumings argues, however, the KPA's rapid withdrawal was strategic, with troops melting into the mountains from where they could launch guerrilla raids on the UN forces spread out on the coasts.". Is that enough to answer the question?
Answer: yes
