As a relatively disinterested foreigner, I view the UK's decline - militarily and otherwise - with some amusement. Put simply, it shouldn't have happened. You had both the intellect and the resources to do so much better for so much longer.
You'll hate this, but it's those of you who are retiring now or retired in the past 15 or so years who must carry the can for breeding a generation of self-centred fools.
Ironic, isn't it? So much potential, so little achievement...
