As clashes between the CPC and KMT intensified, countries such as the United States and the Soviet Union attempted to prevent a disastrous civil war. After the New Fourth Army incident, US President Franklin D. Roosevelt sent special envoy Lauchlin Currie to talk with Chiang Kai-shek and KMT party leaders to express their concern regarding the hostility between the two parties, with Currie stating that the only ones to benefit from a civil war would be the Japanese. The Soviet Union, allied more closely with the CPC, sent an imperative telegram to Mao in 1941, warning that civil war would also make the situation easier for the Japanese military. Due to the international community's efforts, there was a temporary and superficial peace. Chiang attacked the CPC in 1943 with the propaganda piece "China's Destiny", which questioned the CPC's power after the war, while the CPC strongly opposed Chiang's leadership and referred to his regime as fascist in an attempt to generate a negative public image. Both leaders knew that a deadly battle had begun between themselves.
