I also appreciated these lines:
"Across the generations we have proclaimed the imperative of self-government, because no one is fit to be a master, and no one deserves to be a slave. Advancing these ideals is the mission that created our Nation. It is the honorable achievement of our fathers. Now it is the urgent requirement of our nation's security, and the calling of our time."
Echoing one of his earlier speeches in which he said, "The commitment of our fathers is now the calling of our time."
I was trying to remember, and I know you will, was that from his first inauguaral address, or was it from a speech after 9/11?
This is from the Address to the Nation at the National Cathedral, September 20, 2001.
