Political union has numerous non-economic benefits which a trade bloc lacks  Linking countries together politically is something we have done throughout history to preserve peace and ensure consistent channels of communication. Thanks to the European Union not only have millions of people gained greater freedom of movement and a freer flow of ideas: we have also secured very stable relations between a large number of states that previously were often at war with each other. All Member States, since they are tied both politically and economically, have a great interest in preserving stability in Europe and are incredibly unlikely to engage in hostility. Simple economics does not prevent war, as shown by the amount of trade before World War I, but political unions ensure that differences are worked out through dialogue. Because of this, it seems unthinkable for war to happen in the near future, an achievement that has been recognised by the awarding of the Nobel Peace Prize (24). Eliminating the political union would compromise this great achievement.  (24) “The Nobel Peace Prize for 2012”, Announcement, Prize Laureates, The Nobel Peace Prize. 12 October 2012.
