 ::I'm not sure what you mean by using capital letters for Islamic State.  Sometimes the press says, for example, ""The new group, called Islamic State ..."", and sometimes, ""The new group, the Islamic State ..."", but obviously never ""The new group, The Islamic State ..."".  In view of what you say, I think it should be called ""the Islamic State"" in the article's text, but ""The Islamic State"" in headings and infoboxes.  But if I attempt to make any kind of edit on this, I might have my head cut off by the person I mentioned, so will let him fight that one out with others!  At least what you told me is useful information I can quote if necessary when people start disputing any changes.  Thanks.    "
