Read up on the history of the Muslim invasion of Arakan since the 9th century.  Remember that the British, when running India, ARMED the Rohingya Muslims 
before the British fled the Japanese during the pre-WWII invasion of Burma.  The Rohingya Muslims then used those arms in widespread slaughter of Buddhists and Burmese out of spite, retribution, and "holy jihad."  This is what Muslims always have done throughout their 1400 year history.  They start as a minority, and at every opportunity for militancy they might get away with, they start slaughtering the people they hope permanently to displace.  Then of course when the tables turn on them, they whine against "genocide," this time with the help of news agencies.
