This book analyses three major themes: decolonization, sovereignty, and peacekeeping. Their interaction during the national liberation struggle during the Cold War, culminating in the 1956 Suez War, addresses the principle of national sovereignty after World War II in the framework of the UN Charter. The new peacekeeping operations were used in many conflicts, during which the Charter’s theory and application were tested. The rise of the USA as the key Western power and Israel’s special role in the Middle East have created a new confrontational dynamic for the entire region. The interaction between the book’s main themes in the field has led to the principles of peacekeeping in international and national conflicts being reviewed in light of the discredited ‘Capstone Doctrine’. The author argues that state sovereignty is sacrosanct, but humanitarian interventions are equally imperative in his view. Striking the right balance is crucial for managing conflicts. The author:·        offers a well-informed historical account and an authoritative political analysis·        was exposed to UNEF deployments and termination and knows key peacekeeping actors·        draws on original documents, memoirs, and interviews·        includes unpublished photos and previously unavailable documentary material ·        has experience in government and academia
