"The U.S. occupation of Korea, separated from China by only a river, would threaten Northeast China. Its control of Taiwan posed a threat to Shanghai and East China. The U.S. could find a pretext at any time to launch a war of aggression against China. The tiger wanted to eat human beings; when it would do so would depend on its appetite. No concession could stop it. If the U.S. wanted to invade China, we had to resist its aggression. Without going into a test of strength with U.S. imperialism to see who was stronger, it would be difficult for us to build socialism. If the U.S. was bent on warring against China, it would want a war of quick decision, while we would wage a protracted war; it would fight regular warfare, and we would employ the kind of warfare we had used against the Japanese invaders."
