Joshua S Goldstein suggests that empires, analogously to an individual's midlife crisis, experience a political midlife crisis: after a period of expansion in which all earlier goals are realized, overconfidence sets in, and governments are then likely to attack or threaten their strongest rival; Goldstein cites four examples: the British Empire and the Crimean War; the German Empire and the First WOrld War; the Soviet Union and the Cuban Missile Crisis; the United States and the Vietnam War. Suggestions that the European Union is suffering a political midlife crisis have been put forward by Gideon Rachman (2010), Roland Benedikter (2014), and Natalie Nougayrède (2017).
