"At what point in history was Greece in any sense "a British colony"
Of course it wasn't - it was a reference to British Imperialist behaviour in its effort to control the affairs of other countries - "British tourism" in fact - a drift maybe, but not too far.
I could, of course, have mentioned Cyprus, where the British Prime Minister of the day (James Callaghan, I seem to remember) colluded with fascist Turkey to ethnically cleanse the partitioned Northern sector.
