You have to understand the dynamics of the region first before giving it a religious touch.
There are two large tribal groups - Meitei and Kuki. They have been fighting for land and influence for a very long time. Kukis being in minority are demanding status to buy land and settle - which a much dominated Meitei group - who are also in power - are hesitant to do so.
Central govt. is silent mainly because they run state government in Manipur which is led by N. Biren Singh, a Meitei. Their parliament got 60 seats, out of which 40 belong to Meiteis, even though they are only 53% in population.
Now, anyone in b/w all this chaos can twist and turn things for their own ulterior motives. We, as Pakistanis, should stay the PHACK away from all this shit-show and focus on our own issues - especially when our beloved Army portraying themselves as saviour of this nation, under whose nose we have lost half of Pakistan in 1971 and now, having bastard criminals being put on thrones as puppets while they call the shots. Pakistan is the 4th worst passport in the world. We didn't fall this low in a single day - it took millions of good people's silence and their inability to rise against atrocities and injustice.
