So long as these prejudices [religious, racial, national, political] survive, there will be continuous and fearsome wars.
To remedy this condition there must be universal peace. To bring this about, a Supreme Tribunal must be established, representative of all governments and peoples; questions both national and international must be referred thereto, and all must carry out the decrees of this Tribunal. Should any government or people disobey, let the whole world arise against that government or people. (‘Abdu’l-Baha, ‘Selections from the Writings of 'Abdu'l-Bahá’; The Compilation of Compilations, vol. II, Peace)
