One represents danger and the other represents opportunity. Forgive your enemies, but never forget their names. Our growing softness, our increasing lack of physical fitness, is a menace to our security. There is always inequality in life. Some men are killed in a war and some men are wounded and some men never leave the country.
Life is unfair.
Let us never negotiate out of fear, but let us never fear to negotiate. Today every inhabitant of this planet must contemplate the day when this planet may no longer be habitable. Every man, woman and child lives under a nuclear sword of Damocles, hanging by the slenderest of threads, capable of being cut at any moment by accident or miscalculation or madness. It is an unfortunate fact that we can secure peace only by preparing for war. When power leads man towards arrogance, poetry reminds him of his limitations.
