The Lt Col like many of us retired folk is obviously relying on a memory that is itself increasingly unreliable. In any case, even if the Vulcan raids did little but upset the Argies a bit it was still a contribution to the war effort. In fact, they did considerably more than that because after the raid the Argies had to defend BA from air attack. They also were precluded from doing what we did so soon after we occupied Stanley - that is operating fast jets off the airfield. Had they done so the losses to our forces would have been disasterous.
