Would they ever tell us if they'd produced small amounts of nuclear material and used them on the Russians?
All I know is in the last weeks of the war the Aliies were paniacing and desperate to defeat Hitler. I think a large scale bomb was on its way.
Power Lust I think the Nazis were further advanced than most people understand, but you are correct that the Allies retrospectively suppressed knowledge of this. The Dallenbach project for example remains classified to this day.
The Germans had tactical nukes in 1943-44. They were working on a larger bomb. Dornberger disclosed to hidden microphones whilst interned after the war at CSDIC Camp 11 in Wales that Hitler intended more for the V-2 than just 2 tons of high explosives. There were inferences given to the OSS by their informant Respondek that the German Atomic weapon was due for use by October 1944.
In July 1944 Churchill was so fearful of an imminent nuclear attack on England that he warned Hitler that the RAF would retaliate with mass seeding of Anthrax across Germany. The United States amplified Churchill's threat by warning Hitler through Lisbon of an intention by USA to drop an atomic weapon on Dresden unless Hitler sued for peace within six weeks.
Respondek who worked for the Nazi Economic Ministry was arrested following the bomb plot against Hitler on 20th July 1944. In Jail he was approached by Himler to take a peace feeler to Sam Woods in Switzerland.
The reason Germany failed use nukes was not because they lacked the technical competence. In fact an Austrian scientist named Professor Lachner revealed from Argentina after the war that 15 nuclear weapons were built by Germany before the war ended and two of these fell into Soviet hands.
Dresden was targeted in February 1945 because it housed Max Steenbeck's plasma physics laboratory vital to Dallenbach's project and the Allies wanted it destroyed before Dresden fell to the Soviets. In fact the laboratory survived Dresden's bombing and afterwards equipment was evacuated south by Dr Rolf Wideroe to Kreis Ebermannstadt.
