Masarat al-salam wa-diblumasiyat al-425 is a political nonfiction work examining the diplomatic dimensions of the Arab-Israeli conflict, with particular attention to peace efforts and the political consequences surrounding Resolution 425. Written by Ghassan Tuwayni, the book considers how regional actors, international diplomacy, and state policy shaped negotiations and conflict management in the Middle East. The work is best understood as an analytical study of political decision-making during a period marked by war, mediation, and contested claims to security and sovereignty. Its focus on peace and diplomacy places it within the broader literature on Arab-Israeli relations, Lebanese political history, and the role of international institutions in regional disputes. The edition published by Dar al-Nahar lil-Nashr presents the text as a concise Arabic-language study intended for readers interested in modern Middle Eastern politics, diplomatic history, and the evolving frameworks for peace in the region.
