“We shall never forget that it was our submarines that held the lines against the enemy while our fleets replaced losses and repaired wounds.”

Letter to George Washington (August 1778)

As quoted in Il Duce: The Life and Work of Benito Mussolini, L. Kemechey, New York: NY, Richard R. Smith (1930) p. 54. Written just before taking editorship of the Italian Socialist Party newspaper Avanti in 1912.

No Compromise – No Political Trading (1899)
Context: We shall never go wrong if we do what is opposed to the interests of our enemy. On the other hand, we shall almost never go right if we do what our enemies applaud. Historical development is a continuous conflict, a conflict of interests, a conflict of races, a conflict of classes. And if friendship does not count even in ordinary business, how much less so in such a conflict. Good-naturedness and sentimentality have no place in politics. They have never won a victory, but have brought unnumbered defeats. Bluecher’s motto, “Always follow the cannon’s roar and throw yourself upon the enemy,” is the best rule also in.

Foreword, in United States Submarine Operations in World War II. (1949) by Theodore Roscoe, p. v
Context: When I assumed command of the Pacific Fleet in 31 December, 1941; our submarines were already operating against the enemy, the only units of the Fleet that could come to grips with the Japanese for months to come.
It was to the Submarine Force that I looked to carry the load until our great industrial activity could produce the weapons we so sorely needed to carry the war to the enemy. It is to the everlasting honor and glory of our submarine personnel that they never failed us in our days of peril.

1950s, Loving Your Enemies (Christmas 1957)
Context: Jesus is eternally right. History is replete with the bleached bones of nations that refused to listen to him. May we in the twentieth century hear and follow his words-before it is too late. May we solemnly realize that we shall never be true sons of our heavenly Father until we love our enemies and pray for those who persecute us.

1960s, The American Promise (1965)
Context: For Negroes are not the only victims. How many white children have gone uneducated, how many white families have lived in stark poverty, how many white lives have been scarred by fear, because we have wasted our energy and our substance to maintain the barriers of hatred and terror? So I say to all of you here, and to all in the Nation tonight, that those who appeal to you to hold on to the past do so at the cost of denying you your future. This great, rich, restless country can offer opportunity and education and hope to all: black and white, North and South, sharecropper and city dweller. These are the enemies: poverty, ignorance, disease. They are the enemies and not our fellow man, not our neighbor. And these enemies too, poverty, disease and ignorance, we shall over, come.
