They are not exterminating them. Were they intent on that the border with Bangla Desh would be closed and the Rohingyas not allowed to escape. Many of the Rohingyas originated across that border anyway and have been migrating into Burma in part due to extreme poverty in Bangla Desh. They are also using the Koranic mandate to do hijrah- to migrate and to Islamize new lands and populations. I respect the Burmese for actually defending themselves and for being pro-active. The major personality in the resistance calling for suppression of the Mohammedans is a Buddhist “abbot.” That in itself is surprising. He has organized a militia for the purpose of pre-emptive defense and retaliation.
You know a religion is militant evil when you can get Buddhists to put their war face on...
