In an Anglo-German context, it seems to make a difference whether one writes the word with a 'K' or a 'C'. 'Kultur' was the dubious 'high culture' (which often turned into kitsch) pursued by the Nazis. What, then, is 'Cultur(e)'? The British, post-Empire, in pursuit of something they never had to define before? Or a search for something grander a new means of international communication, above creed and nation, no longer dependent on particular letters, of benefit to both the one-time enemies.
As in »having your kuchen (note k & c) and eating it«.
