This book examines Indonesia`s rise as a power of regional and global significance in the context of the altered geopolitics of the AsiaPacific. It explains the fundamental transformation taking place in the international image and behavior of Indonesia as the third largest democracy and the largest Muslim democracy, an ardent advocate of global multilateralism, a proactive leader of the ASEANled regional security architecture and a champion of strategic autonomy and multipolarity. It delves deeper to identify the domestic drivers and spoilers of Indonesia`s success story. The book situates underlying principles of the country`s strategic behavior in the context of its own evolving strategic culture rooted in its historical (civilizational, colonial and postcolonial) experiences and widely accepted beliefs and worldviews.
