I'm surprised no-one has mentioned that despite all that "capability" a number of those countries at the top of the list have spent the last 10 years getting their arses handed to them by tribesmen with IEDs, RPGs and Kalashnikovs.
I hate to use the phrase "asymmetric warfare" but despite all the Staff College teaching on that subject we have demonstrated that when you are equipped for conventional warfare, that's the only tool you have in your bag. Typhoon, Type 45 and Challengers have not exactly proven to be decisive in Afghanistan.
While we are waiting for the war in which our equipment is relevant and effective, we are wasting lives and budget on a never ending series of Procurement White Elephants. This League Table is about as meaningless as it gets.
