The recent endeavors of the European Union have not been as vastly successful as originally hoped. It was hoped that the Euro would be as popular to investors as the US dollar bringing the included nations of the European Union to an equal economic plateau. As mentioned above, this has not been the case and the Euro is not performing in the world economy at all as well as expected . This has shaken the public's confidence in the European Union causing some states to rethink how beneficial European integration in fact may be to them. As a result, certain states, following Denmark's lead, refuse to even join the European Union as it is today . This is a perfect example of the reluctance states
