THS, why?
It implies (to me at least) that you consider a CVS was essential for:
Gulf War 1
The Balkans
Gulf War 2
Afghanistan
Libya
Don't get me wrong - I strongly believe in a capable and significant Navy, Army and Air Force but a single big deck carrier with (at most) 12 aircraft aboard? If we could afford both and another 30 jets to join them afloat then yes, why not have them - it's a big stick to carry - but when we're likely to have one with such a small fleet of fixed-wing aboard it doesn't make sense to me.
With another rather large spending round looming next year, which will be replete with yet more cuts, why not ask the question "why?!"
