The transition from Sukarno's Guided Democracy to Suharto's New Order reflected a realignment of the country's political forces. The left had been bloodied and driven from the political stage, and Suharto was determined to ensure that the PKI would never reemerge as a challenge to his authority. Powerful new intelligence bodies were established in the wake of the coup: the Operational Command for the Restoration of Security and Order (Kopkamtib) and the State Intelligence Coordination Agency (Bakin). The PKI had been crushed on the leadership and cadre levels, but an underground movement remained in the villages of parts of Java that was methodically and ruthlessly uprooted by the end of 1968. Around 200,000 persons were detained by the military after the coup: these were divided into three categories depending on their involvement. The most active, Group A, those "directly involved" in the revolt, were sentenced by military courts to death or long terms in prison; Group B, less actively involved, were in many cases sent to prison colonies, such on Buru Island in the Malukus, where they remained under detention, in some cases until 1980; Group C detainees, mostly members of the PKI peasant organization, were generally released from custody. (As late as 1990, four persons were executed for involvement in the coup. Although the delay was explained as due to the length of the judicial appeals process, many observers believed that Suharto wanted to show that the passage of years had not softened his attitude toward communism.)
