If teh uk has used vtol in many roles (a point i dont question), i suspect it is based on a question of using what you have. It doesnt have any carrier big enough for normal naval aircraft, so vtol is the only real way to go, and it orders more of the same to remain compatible with existing resources.
The UK used to have many large aircraft carriers. This applied to WW2, and the Cold War. The UK required a vast naval presence to neutralise the Soviet threat in the north sea (and block access to the Atlantic).
In the 1960s, the UK planned to continue this theme of maintaining huge carriers. The QE-class was a planned full-sized 50k ton supercarrier.
But you are right, the UK used what it had: It had VTOL so the big carriers were no longer essential!
Big carriers are still desireable, which is why the UK is now acquiring full-sized 60k ton supercarriers.
Point is that VTOL opens the door and allows other solutions.
Regarding the vtol as a response to nuclear weapons, I fail completely to see how a better aircraft could hope to defend against a nuclear missile. It seems to me that it was more a result of general build a better aircraft rsearch than a direct response to nuclear weapons. The timing is more coincidental than cause-response.
You need to read more history books
The VTOL projects (UK, US, USSR) were based on the fear that a pre-emptive nuclear strike would destroy all established RAF & USAF airfields. All three powers concluded that VTOL would reduce the requirement for runways and allow their airforces to continue performing their role after such a strike.
So you see, the original idea behind VTOL was to remove the need for airstrips: Airforces could use carparks or similar!
However, the actual real world effect of having VTOL was that the same idea worked for ships! Suddenly the whole idea of needing runways at sea was obsolete.
The UK has always maintained a fairly large naval airforce and taken associated issues very seriously. It was at it's biggest during the Cold War.
We don't see much of the Russian navy. It is relatively quiet.
The USA has not had VTOL for very long, and still has large numbers of CTOL fighters in service. Complete transition takes time.
