Well, gee! How unfair of the Allies to bomb Germany 24 hours a day so they couldn't use their "more advanced weapons", Doesn't it strike you that if the German's weapons were really all that "advanced", the Allies shouldn't have been able to bomb them 24 hours a day? You watched a TV documentary that claimed the Germans were "very close" to being able to hit the US with a V-2, and you believed it? LOL! Even if they were, and that is highly unlikely, landing a V-2 at random on the US eastern seaboard,isn't going to make a helluva big difference in the war, let alone bring England or the US to "their knees". As for Germany developing an atomic bomb which could fit the warhead of a V-2, only in your wet dreams. !. Germany was never even close to developing an atomic bomb, Because one of the chief German physicists, Werner Heisenberg, screwed up and miscalculated the amount of fissionable material required. As a result, Speer, in 1942, decided not to pursue an atomic weapon. German research was directed at achieving nuclear power for ships. aircraft, etc. 2. The maximum weight of the V-2 warhead was only about 2,200 pounds, while the smallest atomic bomb of the time weighed about 10,000 pounds. Even if they had developed an atomic bomb, it wouldn't fit in a V-2. They would have had to develop a rocket more than 4.5 times larger and more powerful than the V-2 in order to launch an atomic bomb. 3. There would be no point in fitting an expensive atomic warhead to a rocket as unreliable and random as a V-2. No one could predict if the rocket would hit any kind of target, and many of the V-2's actually malfunctioned on launching, coming back down in German territory; not an appealing idea if the damn thing has a nuclear warhead. So no, the Germans weren't even in the ball park for realizing atomic weapons, striking the US, or being able to reverse the course of the war. They were losers when it came to developing effective weapons.
