If Sulu can claim Sabah, Brunei too can claim, similarly Malaysia can claim Singapore, based on history. And again the Red Indians can claim United States of America.

Historian Farish Noor says if the Sultanate of Sulu’s claim to Sabah is based on history, Brunei technically has a greater claim to the state.
Moreover, It’s estimated there are about 60 Suluks claiming to be the Sultan of Sulu – but who’s the legitimate King?

We speak to one man who says he is the righful Sultan – and he doesn’t condone the methods taken by his relatives who are locked in a stand-off in Sabah to reclaim the state.

Ampun Muedzul-Lail Tan Kiram also believes more Suluks are on their way to Sabah to make their own claims for the state.
Dr Farish also says while reports of Malaysia paying the Sulu Sultanate “rent” may be true, the money would be purely tokenstic and wouldn’t give Sulu legal claims to Sabah.
