Robert Menasse at Eurozine:
Creating peace in Europe was a moral ambition that all could share. Yet Monnet was fully aware that moral appeals and trust in people's war-weariness would provide no more lasting security than international peace treaties. His idea, formulated as a plan with the French foreign minister Robert Schuman, was to overcome nationalism by gradually encouraging the nations to abandon rights of sovereignty, until, equally hollowed out and deprived of their very core, they would cease to have a future, hence undermining nationalism definitively. For this to work, supra-national institutions would have to gradually take over from national institutions. This process began with the creation of a high authority that regulated coal and steel production on behalf of the member states. Coal and steel were crucial not only for war but for reconstruction and economic revival. Creating a supra-national authority that controlled these products, ensuring their fair distribution and preventing secret rearmament, was the first step in a planned post-national development that would lead to the political and economic integration of the European nations, prevent them from deviating from the path, and that would ultimately supersede the nations entirely.
“Nationalism has destroyed European culture and civilization.” (Stefan Zweig)
“The nations and their political institutions have proved once and for all that they are not equal to the task of lasting peace and rule of law.” (Jean Monnet)
