I like the brave new Gordy Brown scenario though - brilliant stuff...
Okay you evil Russians, don't forget our nuclear arsenal is out there somewhere, poised to attack you... well okay it might not be if it's in for a refit but that's just a risk you'll have to take... we might be poised to defend ourselves, then again we might not be... tricky little beggars us Brits, ain't we?
And think twice before you pick a fight with us, you evil foreign despots. We'll send our carrier out to get you. Ah yes, well we might not if it's in for a refit but we'll talk to our mates over in France as they said they might lend us a boat... unless theirs is in refit too.
It's enough to strike fear into the heart of any mere mortal.
