Without knowing the specific context in which Churchill used the phrase a second time, it is difficult to provide a definitive answer. However, in general, politicians and public speakers often repeat phrases or slogans for emphasis and to reinforce their message. Repeating a phrase can also help to make it more memorable and to ensure that it is properly understood by the audience.
Churchill was known for his powerful speeches, and he often used repetition to great effect. For example, in his famous "We shall fight on the beaches" speech delivered on June 4, 1940, he used the phrase "We shall fight" multiple times to emphasize Britain's determination to resist Nazi Germany. By repeating the phrase, Churchill was able to convey a sense of urgency and determination that resonated with his audience.
In general, repeating a phrase or slogan can be an effective rhetorical technique for making a point or conveying a message. It can help to reinforce key ideas and to ensure that they are properly understood and remembered by the audience.
