But while our goals were at least temporarily obtained in these and other instances, our successful defense of freedom was due not to the words we used, but to the strength we stood ready to use on behalf of the principles we stand ready to defend. This strength is composed of many different elements, ranging from the most massive deterrents to the most subtle influences. And all types of strength are needed — no one kind could do the job alone.

I hope that all of you who are students here will recognize the great opportunity that lies before you in this decade, and in the decades to come, to be of service to our country. The Greeks once defined happiness as full use of your powers along lines of excellence, and I can assure you that there is no area of life where you will have an opportunity to use whatever powers you have, and to use them along more excellent lines, bringing ultimately, I think, happiness to you and those whom you serve."
