**Analysis**
The text appears to be discussing the concept of international security and its relationship to national security, military power, and economic development. It highlights the importance of balancing military and non-military elements, as well as national and international interests, in achieving international security. The text also touches on the human costs of conflict, including loss of life, economic destruction, and displacement of people. The discussion is quite abstract and theoretical, focusing on concepts and principles rather than specific policies or programs.
