As we have said above, a political system is a sub-system of a larger political system, while, in its turn, it has a number of sub-systems and sub-systems of subsystems. It has been calculated that there are, at least, four levels of political systems and their subsystems. They can be hierarchically arranged as below:
First Level International Political System
Second Level National Political Systems, e.g. Pakistan, China, Iran, Egypt, Algeria, France, Great Britain, Holland, Canada, USA, Mexico, Brazil etc.
Third Level Decision-making sub-system; e.g. governments, political parley (sub-system) Interest or pressure Group (Sub-system)
Fourth Level he individual, as a voter, etc., with his/her interests, demands and supports.
First level: the International Political system. It can be divided, at second level, into several national political systems, such as those of Pakistan, India, China, USA, USSR, Great Britain, France, Saudi Arabia, UAE, etc. There are nearly 160 national political systems or national States in the world today. Thirdly, each of the national political system can be divided into such subsystems as decision-making system or government, party system, etc. Finally, each of the political sub-systems consists of several individual men and women, as voters or participants in political activities. Cadi individual has his or her interests, attitudes, beliefs, values, etc. They link him or her with a political subsystem and national political system, on the one side, and with other social or economic, and other sub¬systems and systems, such as a family, a school, an office, a shop or a workshop, a factory, farm, religious group or community and so on and so forth. Thus every man, woman and child is embedded in a vast political and social systems of his State and society.
