The recent rapprochement between Ethiopia and Eritrea has fundamentally reshaped the relationship between the two countries. The impact of the resolution of the Ethiopia-Eritrea conflict goes beyond the borders of the two countries, and has indeed brought fundamental change to the region. Full diplomatic relations have been restored between Eritrea and Somalia; and the leaders of Eritrea and Djibouti have met in Jeddah, Saudi Arabia. The central question the book attempts to address is: what factors led to the resolution of a festering conflict? The book explains and analyses the rapprochement, which it argues was made possible by the maturing of objective and subjective conditions in Ethiopia and by the trust factor in Eritrea.
