Here is the 1st Paragraph. Enjoy.
WHY IS CYPRUS DIVIDED?
It is necessary to know what happened in Cyprus between the foundation of the Republic in 1960 and the Turkish intervention in 1974, not for historical interest but in order to determine whether the political status of the Greek Cypriot Administration today, and its acceptance by the world is justified. If the Turkish Cypriots had simply withdrawn from the institutions of the Republic in 1964 with no reasonable excuse, and if the Turkish army had invaded in 1974 without any legal right or humanitarian justification, then perhaps the world would be right to treat the Greek Cypriot Administration as if it were the Government of Cyprus. The truth of the matter is however very different.
