Why are many Second World War operations unknown to current politicians and difficult for historians to recover?
Short answerMost politicians have no need to know, while many files were never retained and surviving records can remain buried within a vast archive.
NotesModern politicians are unlikely to receive routine briefings on inactive operations from eighty years ago. Relevant files may be buried or permanently lost because archives preserve only a small fraction of government paperwork. The National Archives may hold only a few percent of everything produced by the British government, despite the collection's enormous size. Common fifty- or seventy-five-year release periods operate as practice rather than a universal automatic rule.
