Singapore's relationship with Indonesia, like its relationship with Malaysia, was built on a foundation of past discord, specifically Indonesia's Confrontation campaign against Malaysia from 1963 to 1966. After President Sukarno (1945-67) was deposed, relations were based to a large degree on Lee Kuan Yew's personal relationship with President Soeharto (1967---). Because bilateral relations lacked an institutional foundation, they were vulnerable to the departure of either leader.
