A major reason that the Chinese army held onto the city as long as it did, even though it was on the brink of collapse, was that China was hoping for Western intervention in the Sino-Japanese War. Western nations had been paying little attention to China's plight since they were preoccupied with the situation in Europe. In addition, most Western nations had little prospect that their intervention would help China in the long run because they believed that China would eventually lose. If China was deemed militarily weak, economically backward, and politically disunited by Western powers, it would not make sense for them to help China when it seemed bound for defeat by Japan.
