The sustainability of the transatlantic alliance lies not so much on the external environment that surrounds it but rather on the will of the people than live within it. Why citizens in France, the UK, Hungary or the US have decided to question that order so openly must surely be one of the central questions that analysts of transatlantic relations attempt to answer. And yet, what one normally finds at the core of analyses produced on the state of transatlantic relations are exogenous structural factors. These are issues like Russian revisionism in Eastern Europe or the rise of China and its geopolitical consequences. On both accounts the argument normally goes as follows: These emerging and revisionist powers pose a particular threat to shared European and American interests.
