The development of International relations together with forces like globalization and technology has brought the world closer to each other. Friendly ties and relations with states create massive challenges during times of conflict. The focus of the paper is on the crisis evolving in the Middle East region and the role of Pakistan in solving those crisis considering relations with its closest allies, political and financial circumstances, and its foreign policy principles. A qualitative research approach with desk analysis technique has been applied to analyse the role of Pakistan as a mediator for the conflict resolution among Middle Eastern countries. The research highlights how the disputes created great problems for Pakistan but it is still striving to resolve conflicts among Middle Eastern countries because maintaining peace and prosperity in the Muslim world has always been a top priority of Pakistan’s foreign policy.

Abstract Water resources in the Middle East region are becoming scarce, while millions of people already do not have access to adequate water for drinking and sanitary purposes. Water resources depletion has become a significant problem in this region that is likely to worsen. Current research by remote sensing analysis indicates a descending trend of water storage in the Middle East region, where agriculture plays a crucial role in socio-economic life. This study introduces an approach quantifying water depletion in the Middle Eastern countries, which are being challenged in the management of their water resources. Furthermore, this paper presents results of a survey assessing the status of water use and supply in Middle Eastern countries and outlines some potential remedies. Specifically, Iran's water use is evaluated and compared with its neighbors'. The water equivalent anomaly (WEA) and total water storage (TWS) depletion are two indexes of water scarcity calculated for Middle Eastern countries surveyed herein. Our analysis reveals that Lebanon, Syria, Iraq, and Iran are countries with very negative water scarcity indexes. These estimates prove that international cooperation is needed to manage available regional water resources and reverse depletion of natural water sources. It is demonstrated herein that virtual water trade can help remediate regional water shortage in Middle Eastern countries.

It is in moments of great upheaval that societies may best be studied. Today, The North Africa and the Middle East region (MENA) finds itself in the most alarming state since World War I. The Oxford Handbook of Contemporary Middle East and North African History is a timely intervention to interrogate the region’s internal dynamics and take stock of its place in world politics. It illuminates afresh dominant historical currents as well as counter-currents that previous accounts have not given their due attention or have failed to notice. Broadly chronological, this volume combines thematic and country-based, multi-disciplinary analysis in order to reconsider half a century of scholarship and to critically examine the defining processes and structures of historical developments from Morocco to Iran and from Turkey to Yemen over the past two centuries.
