Should our fleet by any possibility be de- 

 stroyed, and our country invaded by a 

 foreign foe, it might cost us five billions of 

 dollars and 500,000 lives to dislodge the 

 enemy and to build another fleet such as 

 we would then know we ought to have. 

 Five billions of dollars would build us a 

 navy far larger and more powerful than 

 the combined navies of the world and place 

 us in a position to enforce universal peace. 



The peace advocates are so short-sighted 

 that they do not see that if we build but a 

 few guns, we are obliged to slaughter with 

 them, whereas if we were to build guns 

 enough, we could then make war on war 

 and put an end to slaughter. 



When we have only a few guns, and not 

 enough to prevent war, then we must use 

 them for killing. If we build guns 

 enough, then we prevent war, and the gun 

 is converted from a death-dealing imple- 

 ment into an instrument for saving life.
