Horse puckey. The allies did not develop "V weapons" because they had no need for them. Holding up the Nazi regime as a group of wonder scientists is inaccurate. They tried to push nascent technology so hard because they had no other choice as it was clear early on they were going to lose. So they started throwing Hail Mary passes. The allies did not need to do that. So they didn't.
Once you have air superiority you don't need cruise missiles.
Part of my point was that the Nazis scattered their efforts into a lot of technologies that didn't benefit them, where they could have altered the course of the war had they made those choices more intelligently, (Of course, if they had had that kind of foresight, they never would have started the war at all.)
