Given the assymetric threat that the current political climate attracts, an investment in psy-ops, intel and special forces might provide better defence. I can only imagine that Tony has a thing for 'The Nuclear Club' or that he is concerned about an unforseen future threat.

A billion a year could help a lot of people regard the UK in a better light. Is it still economically viable to hold the world back by force of arms alone?
