Sharia lives in both countries we conquered. It is like winning Europe and handing it over to the Soviets.
Sharia is growing in America, too.
Permitting sharia was a major mistake on our part, but again, I don't think we understood Islam very well when we started on this. Islam is theocratic; that is, it is not only government by the clergy, but government by religious law, where the religious law and the civil law are one and the same.
We were probably understanding it in the sense of an established church, like the Anglican church in England, which does not govern in any way and in fact is governed by the state or state-chosen persons. Islam has never viewed it this way, and we made a major error in thinking it did.
