Lots of people elsewhere are slagging our brave European neighbours for not helping out in AFG. The plusses and minuses of that argument can go on elsewhere, I'm just curious to think about whether we (i.e. UK) would bother to form NATO if it didn't already exist. There doesn't seem to be enough commonality of vision within the Western countries, to make a defence alliance credible any more. Our world views have diverged to the point where I can't see the point of pretending to rely on our neighbours to defend our interests.
