Diplomacy is traditionally carried out behind closed doors, in hushed rooms, with perhaps a bowl of Ferrero Rocher to hand to put ambassadors at ease. Diplomacy 2.0, though, is carried out in public and, like everything else on social media, with a fair amount of sarcasm. 

Public diplomacy has always been an important tool in communicating a country’s policies, values, and culture. However, the means through which these goals could be achieved considerably changed in the last one hundred years, and politicians as well as scholars have had to face new challenges and adapt to a new media era.
