I want to know the answer to the following question:
Who believed that neither side would see a victory at the end of the Korean War?
All the background I'm provided with is that "In the months after the Shenyang conference Peng Dehuai went to Beijing several times to brief Mao and Zhou about the heavy casualties suffered by Chinese troops and the increasing difficulty of keeping the front lines supplied with basic necessities.". Is that enough to answer the question?
