Mohammed bin Salman's purge of prominent figures, and his stated campaign to modernize and reform Saudi Arabia's laws and economy, have encountered both support and opposition globally and domestically. The Kingdom's potential to engage more effectively in the international community remains challenged by domestic and regional issues. Its lack of policy planning has resulted in a burdensome war in Yemen, a combative relationship with Qatar and controversial ties with Israel - all in the context of a muscular competition with Iran. In this examination of Saudi Arabia's foreign policy, Gulf expert Neil Partrick and other analysts address the Kingdom's relations with established and emergent global powers. The book also investigates how factors from identity politics to the prospect of Iranian nuclear weapons determine Saudi foreign policy. In a changing international order, the future and stability of Saudi Arabia are key and an understanding of the Kingdom is more important than ever. For students of the Middle East and international relations, this book provides indispensable insight into Saudi Arabia's engagement with its region and the world.
