"In 1990 the government agreed to the creation of the Autonomous Region of Muslim Mindanao (ARMM), whereby four provinces with Muslim-majority populations voted in plebiscites for a degree of self-rule."
Seems like pretty straightforward, straightlaced, serious stuff from
The Economist, so far.
"This, however, failed to satisfy the aspirations of the main separatist group, the Moro Islamic Liberation Front (MILF-- the insurgency is so old that its acronym predates embarrassment)."
I especially like the fact that it's an Islamic group.
