Summarize and explain the argument King makes in paragraph 46 about "means" and "ends"

Both the means and the ends must be the same. He argues that one cannot drop bombs on a country and hope for a peaceful ending.

Every time we drop our bombs in North Vietnam, President Johnson talks eloquently about peace. . . . But one day we must come to see that peace is not merely a distant goal we seek, but that it is a means by which we arrive at that goal. . . . In the final analysis, means and ends must cohere because the end is preexistent in the means, and, ultimately, destructive means cannot bring about constructive ends.
