Why a hypothetical British atomic strike in 1941 points toward Berlin

If Tube Alloys had produced an atomic bomb in early 1941, would Britain demonstrate it or strike a strategic target such as the U-boat yards?

After a separate test, the panel expects a direct strategic strike, probably on Berlin, to pursue leadership decapitation and a rapid end to the war.

The panel separates testing from combat use because an unproven weapon dropped on enemy territory could fail and expose valuable technology. If Britain already knew the bomb worked, Berlin would offer a stronger strategic target than coastal U-boat yards. A strike aimed at the Nazi leadership might open the way for a government willing to surrender, while prevailing winds also made some coastal targets dangerous for fallout returning toward Britain. In the desperate circumstances of 1941, the panel expects Churchill's government to use a credible chance to end the European war rather than stage a demonstration. This remains a counterfactual assessment of British bombing logic, not a claim that Tube Alloys was close to delivering such a weapon then.
