Read the excerpt from "Keynote Address."

must be ended, as President Johnson said last March,
by patient political negotiation rather than through the
victorious force of arms, even though this may be
unpalatable for those raised in the tradition of glorious

this one must also be solved responsibly. Just as we
shun irresponsible calls for total and devastating military
victory, so must we guard against the illusion of an
instant peace that has no chance of permanence.
