Talk about beating a dead horse.

Many times in the first half of the speech, Churchill mentions either the new members of his cabinet, or filling other positions in the administration in the near future. From the beginning, he mentions the need to "form a new Administration" (2). He then goes on to talk about how the "War Cabinet has been formed of five Members" (5), including "three party Leaders" (6), not to mention that a "number of other positions, key positions, were filled yesterday, and I am submitting a further list to His Majesty to-night" (9).

Remember that when Churchill gives this speech, it's his first time addressing Parliament as prime minister. That means, much like the president of the United States, he's had to replace many of the highest-level people in government to create his own administration. That could have serious consequences for the people he's talking to, not to mention their constituents at home.

Great Britain was already at war. Changing governments can be rough in normal times (i.e., when you're not battling a fascist empire), but when everyone's stressed about fighting, it's a whole different ballgame. Churchill needed to be clear about what was going on and assure the MPs that the administration was well under way to being formed.

So we guess it's a dead horse we're okay being beaten.
