The British have Invaded all but 22 Countries

According to this article in the Telegraph, the British have invaded all but 22 of the 190+ countries on Earth.  They do stretch things a bit far to come up with the numbers though.  They basically use present day countries and their current borders.  Then, if the British have ever invaded any place that is now within those boundaries, they count that country as having been invaded by Britain.  Canada for example has never been invaded by the UK but is counted since territories presently held by Canada have been.

I was also rather surprised that the British have never invaded Luxembourg.
