In Teddy’s words, we must all do our part…”The success of republics like yours and like ours means the glory, and our failure of despair, of mankind; and for you and for us the question of the quality of the individual citizen is supreme. Under other forms of government, under the rule of one man or very few men, the quality of the leaders is all-important. If, under such governments, the quality of the rulers is high enough, then the nations for generations lead a brilliant career, and add substantially to the sum of world achievement, no matter how low the quality of average citizen; because the average citizen is an almost negligible quantity in working out the final results of that type of national greatness. But with you and us the case is different. With you here, and with us in my own home, in the long run, success or failure will be conditioned upon the way in which the average man, the average women, does his or her duty, first in the ordinary, every-day affairs of life, and next in those great occasional cries which call for heroic virtues. The average citizen must be a good citizen if our republics are to succeed.“

We owe it to those who sacrificed in every way before us.
