Iraq is still a sectarian mess. That is a combined protest and celebration. Sunnis are mad as hell at the corrupt Shia government. The Shia are naturally mad that the Sunnis are mad because they were under the Sunni thumb for ages. Both groups are getting tired of the proxy wars.
This is what happens when clever English colonial governments draw borders with the sole purpose at keeping warring groups stuck with each other, so they could co-opt one to subdue the other. Iraq should have been cut into 3 pieces ages ago.
