There has been speculation for some time that this was a possible direction that the new government could take. I really hope that cooler heads prevail, but it would not surprise me that Islamic influences could push the new goverment toward a theocracy. Islam taken to an extreme always seems to go in that direction. And there is nothing that the US can really do to change that; even after going as far as allowing Iraq a chance at a bright, prosperous, and safe new future. Which is just really tragic for everyone involved.
Islam is not compatible with the western world; IMO a world conflict in the future with Islam vs. everyone else is quite likely.
