Mao Zedong predicted that the war would be long and tough. Mao Zedong is certainly one of the few leaders of armed struggle in history who did not promise their followers a quick victory. His frankness dispelled defeatist feelings in broken dreams beforehand. On the other hand, Mao Zedong correctly estimated the great enduring power of revolutionary mobilization backed by China’s human and material resources, thus helping to build people’s more enduring confidence. He pointed out the kind of strategies and tactics that China’s national war would have to employ to sustain itself before it could be integrated into the world war, which included Japanese attacks on the British, the French,the Dutch, and the Americans. He warned that world war was inevitable, though many Europeans and Americans did not think so at that time.
