Read what the CIA has to say about Japan
and then see what they have to say about the UK
Points of note:
1) The percentage of foreign residents in Japan. Just how the CIA worked these figures and whether they included 3rd generation 'foreign' residents and other 'grey areas' into their stats or not, Japan is Japanese. To experience this yourself, try living in a liberal multicultural area of London then moving to a backwater village in the fens.
2) The last few lines on drug imports into the U.K. Anything you'd like to say there chaps?
