True - but very few countries can do that - and the ones that really can are British allies. And while Britain can't, right at this moment, that should be a reasonably short term state of affairs. It is certainly not an ideal situation to be without proper carrier aviation for any period of time but unless Britain goes to war against the US or France, the lack isn't critical from a defensive point of view.
In terms of the Falklands, the changes made to the defences of those islands since 1982 mean there should never be any need for that type of operation again - they are guarded by a lot more than a company of Royal Marines nowadays and there are runways that allow for reinforcement if necessary.
Rarely check out posts about the UK in this forum...so many uninformed posts.
