As President, I will wage this war with the lessons I learned in war. Before you go to battle, you have to be able to look a parent in the eye and truthfully say: "I tried everything possible to avoid sending your son or daughter into harm's way. But we had no choice. We had to protect the American people, fundamental American values from a threat that was real and imminent." So lesson one, this is the only justification for going to war.

And tonight, we have an important message for those who question the patriotism of Americans who offer a better direction for our country. Before wrapping themselves in the flag and shutting their eyes and ears to the truth, they should remember what America is really all about. They should remember the great idea of freedom for which so many have given their lives. Our purpose now is to reclaim democracy itself. We are here to affirm that when Americans stand up and speak their minds and say America can do better, that is not a challenge to patriotism; it is the heart and soul of patriotism.

A couple quotes from Kerry's speech that ring true.
