They were many years away from an atomic weapon. It's been discussed before.
A simple comparison of the massive Manhattan project to the German effort (one very basic reactor in a cellar under a pub) should be the non-scientific evidence.
Not only that Steve but it is well documented that German atomic bomb research made a very fundamental error quite early on regarding the amount of fissile material needed to provoke and sustain the chain reaction.
Heisenberg wasn't the only German scientist working on this but he was the leading one and as far as I can see the error was his and it skewed everything that came after it.
Throw in the lunacy of exiling a large chunk of the world's leading nuclear scientists just because they were Jewish or part Jewish - and compounding this by just letting them go to work for the allied countries - and yes the crude 'chandalier nuclear pile' at Haigerloch is a perfect illustration how far away they were how incomparable the German effort was to the Manhattan project.
