I don't know if anyone has mentioned this as I have arrived late to this thread and don't have the time or patience to read every reply but...
The phrase "under god" was not in the original Pledge of Allegiance. It was added during the McCarthy era to help root out communist children?
I guess they thought there was no way possible a communist could ever believe in God, totally ignoring all the churches in Russia.
This was of course swiftly approved in by Congress, because if you voted against it you were obvously a Godless Communist.
