Hi Neptunus Rex,
The war in Europe had been won, but the war in the East had not. In 1945 Britain was still very much at the heart of of global empire much of which was in the East. Britain was still very much still at war. The Election of 1945 was held (for the most part) on 5th July, the first atomic bomb was not dropped until 6th August. As far as the British public were aware, at the time of the election Britain was still very much engaged in a World War. What was your point?
