Ever since the Separation on 9th August 1965, the principal leaders of Malaysia and Singapore have expressed the view that their separated states would be compelled by the forces of historical, geographical, economic and social ties to reunite some day. When this would be accomplished has not been clearly defined nor has the manner of their reunification been suggested. Tengku Abdul Rahman, the Prime Minister of Malaysia, merely stated that Singapore would be welcomed back sometime in the future, while Lee Kuan Yew, the Singapore Prime Minister, admitted that it could be a task for the next generation to seek reunification. However, both were hopeful that at some future date circumstances would be more conducive than they were prior to 1965, for another attempt at merger. It is generally agreed that the Separation was a political separation arising from the incompatibility of the political views of the Alliance-controlled central government and the state government of Singapore in the hands of the People's Action Party (PAP). It has also been implied that the fact of their interdependency in several basic fields even after Separation could well provide a strong basis for some form of reunification.
