Context: For many South Koreans today, the Korean War is little more than a tragedy of the past or a tale in abstraction. For others, it is a trauma best forgotten. But on Memorial Day, the South Koreans, as a nation, must not forget the suffering and sacrifice in their national historical experience. The lessons of the most traumatic past must be learned and continually relearned, not only to prevent such a tragedy from repeating itself, but also to honor, as one nation, those who made our freedom possible, and to remember that freedom is certainly never free.

Context: Do we call this the land of the free? What is it to be free from King George and continue the slaves of King Prejudice? What is it to be born free and not to live free? What is the value of any political freedom, but as a means to moral freedom? Is it a freedom to be slaves, or a freedom to be free, of which we boast? We are a nation of politicians, concerned about the outmost defences only of freedom. It is our children's children who may perchance be really free.
