You would put the debate aside. I would question the lifeblood of this country, if the debate no longer raged. The facts can always be blurred. Only the emotions are real. Our beliefs are colored by our experiences and our view of what actually happened.
Every view is correct to the person that holds it.
Hold on to your viewpoint and proclaim it to the world. Vietnam means anger, resentment, and controversy. Democracy was not preserved because of the war in Vietnam. Democracy has been preserved because of the debate over that war. As long as people in this country refuse to agree with each other, democracy will be preserved.
