The art of successful democratic politics requires the ability to correctly identify the interest groups, the nature of social conflicts and to balance the relations among them peacefully. It also includes the ability to handle power and the fall from the power. The economic wealth of a nation or the lack of it cannot be the criteria for the practice of democracy. Democracy can be implemented in rich and poor countries alike. Perhaps the only condition that is required is to accomplish one or a few of the necessary revolutionary steps.
Democracy has little to do with political borders or with the existence of the state.
Democratic systems do not deal with these issues. National borders are a datum, a given. They are a framework within which policies are made and implemented. Coercion does harm democracy. Democratic politics does not relate to the existence of the state or its indivisibility.
