In one of the splendid essays brought together in his Personality in Politics, published just after World War II, British politician and civil servant Sir Arthur Salter speculates about why the USA failed to ratify the League of Nations Covenant, the brainchild of US President Woodrow Wilson. First, Sir Arthur suggests, Senator Henry Cabot Lodge, a one-time supporter of the idea behind the League, was embroiled in “bitter personal enmity” with Wilson, for reasons that have long remained unclear. Sir Arthur suggests that Lodge’s support could have made a decisive difference: it would most likely have resulted in further support by seven more senators, which would have been enough to secure the required two-thirds majority in the US Senate. But the personal relationship between Lodge and Wilson was such that this never happened.
