Very very simplistic and a bit stupid too. By your rational, since the AAC and CHF have lost less people in Iraq and the Stan than the RAF then they too should be disbanded???
I did say it was simplistic, but you have avoided answering the main point. If you have a fixed sum of money would you be happy, and I mean happy, to tell the wife of a fallen soldier on the ground that he died in a substandard vehicle, or incomplete body armour, so that the RAF could keep some assets which might one day be important, in a theoretical threat, but today are not going to save lives ?
