analysis: The text appears to be discussing the global arms race, military spending, and the concentration of military power among a few countries and alliances. The language used is technical and focused on military concepts, such as R&D and trade. The report also mentions the difficulties in obtaining complete data on military expenditures due to differences in statistical information and definitions. This suggests that the text is more focused on military and security issues rather than economic or social development.
