Amen, how comforting it is to leave things in the hands of the Almighty.
The losers in this conflict will be eaten.
The myth of the Nobel Savage at peace with his neighbors and his environment is just that a myth:
If the world is more peaceful now that it was in the past, it is due solely to the Pax Americana. If Hussein destroys our ability to enforce it, hell will be out for breakfast.
This is par for the course with Papuan tribes. While some are peaceful, many others are warlike. And this display of bows, arrows, and improvised shields is not for show. These guys will kill each other if given a chance.
I worked with a guy who lived in PNG for many years.
The stories he told were frightening. "Civilization" is not something these people are ready for.
Update from this clash, in case anyone cares: one killed (arrow to the chest), 15 wounded. Cause of conflict, per Indonesian authorities: one tribe challenged the other to fight. No other reason given.
