The army must become one with the people so that they see it as their own army. Such an army will be invincible, and an imperialist power like Japan … - Mao Zedong

日本现在用战争来压迫，要完全断绝中国革命的进路，所以不得不举行抗日战争，决心要扫除这个障碍。障碍既除，政治的目的达到，战争结束。障碍没有扫除得干净，战争仍须继续进行，以求贯彻。例如抗日的任务未完，有想求妥协的，必不成功；因为即使因某种缘故妥协了，但是战争仍要起来，广大人民必定不服，必要继续战争，贯彻战争的政治目的。因此可以说，政治是不流血的战争，战争是流血的政治。

My closest friend and brother – this world is lucky to have a great personality as Kim Il Sung. This causes my boundless happiness. The fate of the world revolution and the international communist movement are on your shoulders, Comrade Kim Il Sung. I wish you long life and good health.

Man's social practice is not confined to activity in production, but takes many other forms--class struggle, political life, scientific and artistic pursuits; in short, as a social being, man participates in all spheres of the practical life of society. Thus man, in varying degrees, comes to know the different relations between man and man, not only through his material life but also through his political and cultural life (both of which are intimately bound up with material life). Of these other types of social practice, class struggle in particular, in all its various forms, exerts a profound influence on the development of man's knowledge. In class society everyone lives as a member of a particular class, and every kind of thinking, without exception, is stamped with the brand of a class.
