I'm glad you have such joy over this. Personally, I never doubted for an instant that she'd be set free. As soon as I saw that she worked for the Christian Science Monitor, I knew her kidnappers would never hurt her. Why injure an ally? Over and over, I heard their threats, and just thought "promises, promises." These fascist sympathizers are safe as a babe in arms, when in the hands of their islamic captors.
With more info, I believe my cynicism was amply justified. BTW, she didn't go to Iraq as a reporter; she had worked as a reporter for a different paper earlier when she was just out of school, got laid off, and then went to Iraq with some kind of nebulous (and probably terrorist supporting) non-profit. Then she started filing stories for the Monitor.
She took to wearing the Islamic get-up long before she was "kidnapped" and obviously does not intend to change it now that she has been released. In fact, I noticed that they had given her a festive new pastel-colored outfit. Another sign of their incredible thoughtfulness.
