Which quote from Churchill’s speech “The Sinews of Peace” indicates the need to build up the military in the face of the Soviet threat?

Indeed they must do so or else the temple may not be built, or, being built, it may collapse, and we shall all be proved again unteachable and have to go and try to learn again for a third time in a school of war, incomparably more rigorous than that from which we have just been released.

Neither the sure prevention of war, nor the continuous rise of world organization will be gained without what I have called the fraternal association of the English-speaking peoples.

From what I have seen of our Russian friends and Allies during the war, I am convinced that there is nothing they admire so much as strength, and there is nothing for which they have less respect than for weakness, especially military weakness.

I do not believe we should all have slept so soundly had the positions been reversed and if some Communist or neo-Fascist State monopolized for the time being these dread agencies. The fear of them alone might easily have been used to enforce totalitarian systems upon the free democratic world.
