The fact of the matter is that these people who did this did this in the name of their god. I don't care to comment on whether they practice a rogue form of Islam or not, but they serve a false god, they did not do this destruction in the name of our God.
Now obviously God, in His permissive will, allowed it to happen. And it is being used for good. I look at this as God using it as a wake-up call, but don't pin the cause of this on Him.
