analysis: The text appears to be related to a diplomatic correspondence, specifically a letter from the Permanent Representative of Lebanon to an unknown recipient. The context suggests that it may be related to a political or international situation, possibly referring to a crisis or conflict in the Middle East. Given the date (1968) and the reference to a specific region, it is likely that the letter is discussing a political or international issue rather than an economic, social, or scientific topic.
