To add on my previous response, i think this quote by Mao Zedong from the time of the japanese invasion of China is quite relevant on this:

"Can a Communist, who is an internationalist, at the same time be a patriot? We hold that he not only can be but also 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. For the wars launched by the Japanese aggressors and Hitler are harming the people at home as well as the people of the world.

China's case, however, 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 defense 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."

As you see, Mao clearly states, as indicated by the "" around the word "patriotism", that the so called "patriotism" of the imperialists is false, that not only do the invaded and oppressed have the patriotic duty to fight back, but also the working class of the invader countries has the patriotic duty to fight back against their own government, since the war doesnt benefit them either. Thus, as Mao states, "[communists] not only can be [patriots], but also must be [patriots]" and this is fully compatible with internationalism. And this makes sense, the workers of the world have the same interest, to achieve socialism and then communism, so it only follows that by fighting for the interests of your countrys workers, thus being a patriot, you are also fighting for the interests of the workers of the whole world, thus being an internationalist.
