In Europe and with potential world impact there are the problems of Italy which have not gone away. Last year there was some attention to the serious situation there and comment. But we have not heard much lately.
Italy is a relatively new country, only around 150 years old since it was brought together by nationalist movements and the urge for an Italian identity. It has had its troubles, largely arising from two world wars that it became involved in and which led it into the European Union and the Euro block.
