## TOP SEGRET ## III. Estimative Intelligence Reporting ## A. National Estimates National estimates, those community-coordinated reports which attempt to assess a foreign nation's intentions, future policies, or capabilities, are the most important finished intelligence product of the intelligence community. From its earliest days, OSI has been heavily involved in the production of these estimates. Inasmuch as estimates are the result of community participation, OSI's participation has generally been through normal community mechanisms, i.e., the SIC, JAEIC, and GMAIC of USIB. In the early days of OSI's existence, however, OSI produced estimates in two quite separate ways. One path was for estimates that related to the field of atomic energy. These were processed through JAEIC (then a subcommittee of the SIC) to the IAC (now USIB) without ONE participation. For all other types of estimates, the path was from OSI through the SIC and later GMAIC mechanisms to ONE and subsequently to USIB. ## 1. Nuclear Estimates Among the most important early OSI production were the early estimates of Soviet nuclear capabilities. These estimates were produced independently of the normal NIE mechanism and to a great extent independently of the TOP SECRET
