Some quotes I found moving and true:

So it is the policy of the United States to seek and support the growth of democratic movements and institutions in every nation and culture, with the ultimate goal of ending tyranny in our world.

The great objective of ending tyranny is the concentrated work of generations. The difficulty of the task is no excuse for avoiding it. America’s influence is not unlimited, but fortunately for the oppressed, America’s influence is considerable, and we will use it confidently in freedom’s cause.

I ask our youngest citizens to believe the evidence of your eyes. You have seen duty and allegiance in the determined faces of our soldiers. You have seen that life is fragile, and evil is real, and courage triumphs. Make the choice to serve in a cause larger than your wants, larger than yourself and in your days you will add not just to the wealth of our country, but to its character.

We go forward with complete confidence in the eventual triumph of freedom. Not because history runs on the wheels of inevitability; it is human choices that move events. Not because we consider ourselves a chosen nation; God moves and chooses as He wills. We have confidence because freedom is the permanent hope of mankind, the hunger in dark places, the longing of the soul.

History has an ebb and flow of justice, but history also has a visible direction, set by liberty and the author of Liberty.
