War is the highest form of struggle for resolving contradictions, when they have developed to a certain stage, between classes, nations, states, or political groups, and it has existed ever since the emergence of private property and of classes.

The agricultural co-operative movement has been a severe ideological and political struggle from the very beginning. No cooperative can be established without going through such a struggle. Before a brand-new social system can be built on the site of the old, the site must be swept clean. Invariably, remnants of old ideas reflecting the old system remain in people's minds for a long time, and they do not easily give way. After a co-operative is established, it must go through many more struggles before it can be consolidated. Even then, the moment it relaxes its efforts it may collapse.
