Soeharto came to power when the country was in a mess, partly because of the communists influence during the time of his predecessor, Soekarno.

Sukarno had used the Communists to hold power and would have ultimately lost Indonesia to them if he had continued to rule. Indonesia in 1968 was very much part of the Viet Nam War.
