Sunnis really have two choices:
1) Win assembly seats in December and make amends to constitution
2) Keep fighting
If they choose #2 at this juncture of the political process prior to December elections, the Shiites and Kurds won't be silent spectators any more. The hammer will come down.
So, either way, Sunnis will be brought back in line.
Let's not forget what is making the Sunnis so upset - they used to be able to exploit and dominate the Kurds and Shias. Now they're going to be just one of three groups sharing power in the new Iraq. They have to understand, or be made to understand, that there is no going back to their previous dominance.
