My consideration is not fiscal. Read the link I provided. You can think of carriers in terms of lives. You can think of it in terms of NHS service quality.
You are back at nebulous feelings stuff (and frankly, the empire was crumbling and Musketeer wasn't really important to that process - India had already broken away years earlier).
Can you put a price on that? No. And thats the problem.
No, it's not. I did already show that the burden on proof is on your side, not mine.
If that was the case, we wouldnt build a nuclear deterrent either. Costs money, never be used, right?
That's about deterrence. I did already show that the carriers are inefficient for deterrence of attack against UK or NATO, so deterrence is no argument pro carrier.
I will keep insisting that you either accept the fact that you are basing your opinion on feelings rather than ratio or do the impossible; actually build a ratio by providing a proper cost:benefit analysis. Again, the burden of proof is on you.
