When you consult books about Liberal and Liberal Democrat party history about the birth of our “Internationalism”, European “Federalism” and our thesis that stand-alone nationstates (and “narrow nationalism”) become more and more obsolete, you discover a surprising fact.
According to Michael Steed’s chapter “Liberal Tradition” in Don MacIver’s bundle “The Liberal Democrats” (from 1996), it was in the comprehensive policy survey “The Liberal Way” of 1934, that we stated that in future, “narrow nationalist” parties everywhere would face parties, the Liberals firmly among them, supporting the growing, factual interdependence as best policy basis. Philip Kerr, marquis of Lothian, said (1935): “the only final remedy for war is a federation of nations”. But personal guilt about having himself written the War Damages clause in the Versailles Treaty made Kerr become an advocate of appeasement to Germany, a Liberal dissident, until the Munich Agreement.
Both Chris Cook’s history of the Liberals in 1900-’76, and Robert Ingham & Duncan Brack’s authoritative bundle “Peace Reform & Liberation” (PRL; 2001) tell that this “interdependence makes collectivism better policy”-idea was formulated in a phase of disintegration of the Liberal party (the split about the 1931 National Government; desertions to the National Liberals and Labour; loss of seats).
