Considering that comes from the Telegraph, and given their and the author's anti-Europe agenda, as well as the hint of hear-ye-end-of-days-triumphalism at the grand folly of those continentals, I would be inclined take that article with a pinch of salt.
It could still be a good analysis and prediction but it's difficult to get away from the suspicion that a good deal of perverse wishful thinking has motivated the author.
