How about a cost based analysis of the influence it provides against that which could be achieved through other (perhaps more socially and economically constructive) means?
Hopefully, but it will (or ought to be) for more than the British expeditionary appetite.
My point exactly, we don't have the "capability" to match our "will".
Not so sure about this, is possession of a nuclear detterrent an entrance requriement to the Security council -if so, where are the Israeli, Indian and Pakistani seats? Secondly, if millitary capacity and "Global Policing" more generally are requirement and raison-d'etre, when have Russia or China ever "coerced" malefactors though military means?
Edit: China and (in practice) Russia fundamentaly resist any attempts to meddle in the internal affairs of other states. Not a great Policeman if you won't go into someone's house...
