like my post above... the sultanate of sulu are part of the tausug tribe and the MNLF are mostly tausug, thats why nibuwag ang MILF were mostly maranao's... and also most member sa Royal Sultanate Army are also member of MNLF and misuari itself has close ties to the kirams...
and also the reason why MNLF was established it was after the Jabidah Massacre... which is the operation to disrupt and claim sabah...
