Thus, ideology is a rounded-out single harmonious whole, a system of thought that permeates all aspects of life. Marxism-Leninism is a science for social change. In its essence, it represents the unity of revolutionary theory and revolutionary practice However, Marxist-Leninist ideology is not the same in each country. The general law that under capitalism there are the exploited and exploiters locked in class struggle is the same for all capitalist countries. However, the status of the class struggle, the objective conditions, are different for each country.
Ideology has a national character because it reflects the specific racial and national composition.
It reflects the unique status of the class struggle in each country. Thus, there must be a national element in the application of ideology. We have to develop our applications based on our own objective situation, our history and experiences. For example, when we apply our science to the study of the steel industry of any capitalist country the general laws apply. But the history, conditions and problems, are not the same in the U.S. and Japan.
