isbn: 9870571235940 discusses the issues of liberty David Kirkwood (wiki) perhaps is a better illustrator of this then the rather bad wiki example i ‘cite’. Liberty is a loaded word. Liberty to or from.
Liberty or a British view of it depends upon who you are, and who deals with you. The book which starts with the civil war, argues that in 1914 liberty died. Whether or not you agree with that or not it is fair to say that both left and right hate liberty and both have failed to manage the economy without boom and bust. This book (my blog) might help with that.
Liberty can be called a lost cause when places without liberty suggest that Britain is doing it right, and any criticism (from) is seen as bad.
The book loses it way towards the end but points that (to) is much better in liberty than (from) and that tolerating fringe groups causes more problems for liberty who may find that liberty is bad for them.
Preventing liberty (from) depends on several factors, and although bad leadership can be blamed for a few misunderstandings is probably best summed up by Niccolò di Bernardo dei Machiavelli , and an example of that was in Vietnam where both ruling parties ‘misunderstood‘ how things worked.
Or the state creates a boogeyman, The Ladens are a case in point, but the Boogeyman (or his replacement) but do have a shelf life.
Neither of which do much good for politicians perceptions.
