It is worth adding that the expansion of NATO to include Poland and the Baltic states took place with no democratic input from the populations of the existing members. Bearing in mind the commitment of mutual defence that being a member of NATO brings, and bearing in mind the difficulties that we have keeping people happy on the 'economic union' that we are part of. It is no surprise that a lot of people are uncertain whether they support a 'defence union' that has moved right up to the borders of Russia.
