this quote came up recently with all the online patsoc bs, and I found it useful

Can a Communist, who is an internationalist, at the same time be a patriot? We hold that he not only can be but must be. The specific content of patriotism is determined by historical conditions. There is the “patriotism” of the Japanese aggressors and of Hitler, and there is our patriotism. Communists must resolutely oppose the “patriotism” of the Japanese aggressors and of Hitler. The Communists of Japan and Germany are defeatists with regard to the wars being waged by their countries. To bring about the defeat of the Japanese aggressors and of Hitler by every possible means is in the interests of the Japanese and the German people, and the more complete the defeat the better. This is what the Japanese and German Communists should be doing and what they are doing. For the wars launched by the Japanese aggressors and Hitler are harming their own people as well as the people of the world. China’s case is different, because she is the victim of aggression. Chinese Communists must therefore combine patriotism with internationalism. We are at once internationalists and patriots, and our slogan is, “Fight to defend the motherland against the aggressors.” For us defeatism is a crime and to strive for victory in the War of Resistance is an inescapable duty. For only by fighting in defence of the motherland can we defeat the aggressors and achieve national liberation. And only by achieving national liberation will it be possible for the proletariat and other working people to achieve their own emancipation. The victory of China and the defeat of the invading imperialists will help the people of other countries. Thus in wars of national liberation patriotism is applied internationalism.
