The book entitled Modernisation of National Security in South East Asia is the most comprehensive and informative study about the process of modernization of national security system of South East Asian countries. The authors give a detailed account of the crisis and correction in security policy in this region. The security situation in Southeast Asia is remarkably complex, with multiple forces and trends emanating from within the region and impacting on it. The forces at work fall into two broad categories. One involves globalized, transnational, and multinational factors, such as rapid economic change with profound implications for political stability; the sudden emergence of militant Jihadist networks that have mounted violent attacks against the political and cultural status quo in much of the region.
