Why are Buddhists in Burma (Myanmar) attacking and killing Muslims and destroying their communities?
One thing for sure is there is nothing "spontaneous" about it.
Organized crowds all show up at the time and place armed and do their "work" in a coordinated fashion.
The police watch, stand by, and do nothing.
The government which certainly has the capacity to stop it not only does nothing, but also praises the so-called Buddhist leader Ashin Wirathu who openly advocates it.
What's it all about?
1. Violent push back from Muslims (adding to the myth that Muslims are "naturally" violent.)
2. The military will need to intervene to "save the day" - and coincidentally slow down the move to democracy there
3. Drug production and export will through the roof. (The massive drug-hungry China market is just across the border.)
