Miquelon is politically part of Europe, through a quirky bit of French colonial history. But it's obviously not geographically in Europe. In a similar way, Israel takes part in the Eurovision Song Contest. I suppose Israel, in this case, is culturally part of Europe, though clearly not a geographical part. Gets a bit absurd if you start including politics and culture...you might end up saying North America is part of Europe as well, which would be very confusing.
