I assess this book to be a repository of historical facts concerning the geopolitical landscape, intertwined with the author's personal experience. The narrative is presented candidly and structured meticulously, encapsulated within the realm of flawless intelligence science.

This book stands as a significant work in the literature, encompassing knowledge, experiences, and professional contributions in the field of intelligence, while also providing a profound and comprehensive exploration of the culture and environment of Islamic boarding school students (santri). 

Mr. As'ad successfully presents a unique genre of memoir: a combination of the universal ethos of “cogito ergo sum” on one hand and the distinctive cultural wisdom and spirituality of an Indonesian national on the other. Therefore, this book holds a multidimensional significance, serving as both a source of knowledge and cultural insight. Reading this book invites us to embark on a cultural journey within a society and nation undergoing transformation and facing crucial moments for its existence and continuity.

“I am acquainted with the author of this book, someone who possesses high integrity and professionalism. The content of this book can elucidate the extent of the author's capabilities, breadth of experience, and knowledge in the field of intelligence. I can attest to this, not only during their service but also through their book. Each topic, event, or issue is analyzed with a deep and intelligent logical approach to present a comprehensive event horizon. We do not just gain meaning from an event, nor merely record the event, but also a guiding vision for that event. This is the brilliance of the book.”

Major General TNI (Ret.) Syamsir Siregar, former Head of BIN 2004 - 2009.
