...consistent with that nation's behaviour. (I do note spelling :>)

Gee Charmion... nations don't 'behave' as units. Some sad components OF nations shout louder and cause other components to be painted with a broad brush. Even in Germany in 1943, there were many who knew things were seriously headed into evil and danger... and many who spoke up didn't live to see 1945.
   In another forum..(in USNET).. that I follow, several Brits regularly characterize anything American, from politics to spelling to music, as decedent or foolish... or worse.
As to "closest"... that word is ambiguous unless explained in context. I also note that those in the UK still refer to 'miles' and 'inches' in many contexts. I admit that a sane decimal system would be a reasonable thing to introduce, but 1)It would be durned expensive to change over... and 2)We have this awkward thing called "states rights" which allows Alabama & Texas...etc. to do almost everything differently from Oregon or Arizona...etc.

   I know the history and reasoning behind "states rights", but that very history and the rules governing it make it extremely hard to change the system! Alabama & Texas...etc. can disrupt attempts to be sensible. Thus we have guns and abortion restrictions and fuel by the gallon and the electoral college... and when I stand on my soapbox in the park and shout the ** truth**, I get mostly ignored... *wry grin*
   There are philosophical and logical terms for that quandary, but "shrug"
