As we address these challenges – and others we cannot foresee tonight – America must maintain our moral clarity. I have often spoken to you about good and evil. This has made some uncomfortable. But good and evil are present in this world, and between the two there can be no compromise. Murdering the innocent to advance an ideology is wrong every time, everywhere. Freeing people from oppression and despair is eternally right. This nation must continue to speak out for justice and truth. We must always be willing to act in their defense and to advance the cause of peace.

Farewell speech to the nation (January 2009)
