Sollicitudo Rei Socialis §20

²⁰ If at this point we examine the reasons for this serious delay in the process of development, a delay which has occurred contrary to the indications of the Encyclical Populorum Progressio , which had raised such great hopes, our attention is especially drawn to the political causes of today's situation. Faced with a combination of factors which are undoubtedly complex, we cannot hope to achieve a comprehensive analysis here. However, we cannot ignore a striking fact about the political picture since the Second World War, a fact which has considerable impact on the forward movement of the development of peoples. I am referring to the existence of two opposing blocs, commonly known as the East and the West. The reason for this description is not purely political but is also, as the expression goes, geopolitical. Each of the two blocs tends to assimilate or gather around it other countries or groups of countries, to different degrees of adherence or participation. The opposition is first of all political, inasmuch as each bloc identifies itself with a system of organizing society and exercising power which presents itself as an alternative to the other. The political opposition, in turn, takes its origin from a deeper Opposition which is ideological in nature. In the West there exists a system which is historically inspired by the principles of the liberal capitalism which developed with industrialization during the last century. In the East there exists a system inspired by the Marxist collectivism which sprang from an interpretation of the condition of the proletarian classes made in the light of a particular reading of history. Each of the two ideologies, on the basis of two very different visions of man and of his freedom and social role, has proposed and still promotes, on the economic level, antithetical forms of the organization of labor and of the structures of ownership, especially with regard to the so-called means of production. It was inevitable that by developing antagonistic systems and centers of power, each with its own forms of propaganda and indoctrination, the ideological opposition should evolve into a growing military opposition and give rise to two blocs of armed forces, each suspicious and fearful of the other's domination. International relations, in turn, could not fail to feel the effects of this "logic of blocs" and of the respective "spheres of influence." The tension between the two blocs which began at the end of the Second World War has dominated the whole of the subsequent forty years. Sometimes it has taken the form of "cold war," sometimes of "wars by proxy," through the manipulation of local conflicts, and sometimes it has kept people's minds in suspense and anguish by the threat of an open and total war. Although at the present time this danger seems to have receded, yet without completely disappearing, and even though an initial agreement has been reached on the destruction of one type of nuclear weapon, the existence and opposition of the blocs continue to be a real and worrying fact which still colors the world picture.
