But in saying that you're completely misunderstanding the whole point of the Vulcan and the V-Force. Yes, it was designed as a weapon of mass destruction but that was necessary in order to provide a credible (and visible) deterrent. Make no mistake, the Soviet Union was prepared to use nuclear weapons against the West (there are many post-unification sources that will illustrate this quite openly) and the only credible way of ensuring that nothing like that would happen, was to have the ability to strike back with decisive force.
Yes, the V-Force was small when compared to SAC but it was far closer to Moscow, could react more swiftly and would have (had it been needed) been at the very forefront of a retaliatory attack on the Soviet Union. The Soviets knew this, and so there is no doubt that the Vulcan was worth every penny that was spent on it, at a time when the country was financially crippled. By any standards the Vulcan was money well spent because we're all still here to talk about it half a decade later.
Civilian aircraft might well be just as interesting in terms of design and appeal, but the Vulcan was much more than that. Yes, it was big and noisy and awe-inspiring to look at, but more importantly it was capable of doing the job that it was designed for, and it did it with huge success. We know this because we weren't all killed a long time ago.
