In bygone days, officials in some European nations had a way of emphasizing that their forms of government would endure. When a sovereign died and a new one was being crowned, the cry was, “The king is dead — long live the king!”Sadly, so it is with Islamic terrorists. There was rejoicing among many in the Middle East this week, at the news from Raqqa, Syria. That city, long the unofficial capital of ISIS, has been liberated by U.S.-backed forces. ISIS lives, however.
