Aceh's battle for independence from Indonesia is an issue of separatism. Aceh was never successfully incorporated into the Dutch East Indies like the other provinces. It had remained independent from day one - even the Japanese did not succeed in taking away its freedom.
The lack of outside support over Aceh's fight can perhaps be attributed to the fear that one too many Muslim countries may mean opportunities for terrorism and religious extremism.
This fear also arises due to failure to recognise that if these new Muslim states are well-managed, they too can survive as democracies. The smallest Muslim country, the Maldives, is surviving well as a partyless democracy.
Malaysia should lobby the United Nations for the independence of Aceh, Moroland and Pattani - three Muslim states that lost their freedom to Asean imperialists, namely Indonesia, the Philippines and Thailand.
While territorial sovereignty should be respected, this should not extend to annexed territories. Aceh was annexed in 1945 when Indonesia became independent. Moroland was taken by the Philippines' then American colonial rulers in the 1900s. Thailand (Siam) annexed Pattani in the 1900s too.
