Look at it from another perspective: Hitler - rigorous, highly autonomous, giving people the appearance of majesty and toughness. It can be used to gather the power of the country under militarization at that time.

Roosevelt smoked - leisurely, relaxed, giving people the image of being confident. Although the country was already at the cusp of the storm at that time, it still gave people a sense of trust.

How much did Churchill drink every day - Europe fell, and enemy soldiers faced each other across the sea. The people are panicked and morale is low... This move was intended to give the people stability after his speech and not take the enemy seriously.
