Let's face it. Let's talk sense to the American people. Let's tell them the truth, that there are no gains without pains, that we are now on the eve of great decisions, not easy decisions, like resistance when you're attacked, but along, patient, costly struggle which alone can assure triumph over the great enemies of man - war, poverty and tyranny - and the assaults upon human dignity which are the most grievous consequences of each.

When there is no enemy within, the enemies outside cannot hurt you.

When there is no enemy within, the enemies outside cannot hurt you.

If appeasing our enemies is not the answer, neither is hating them... Somewhere between the extremes of appeasement and hate there is a place for courage and strength to express themselves in magnanimity and charity, and this is the place we must find.

Know how to use your enemies. A wise man gets more use from his enemies than a fool from his friends.

Trust the friends of to-day as if they will be enemies to-morrow.

A wise man gets more use from his enemies than a fool from his friends.

The nuclear arms race is like two sworn enemies standing waist deep in gasoline, one with three matches, the other with five.

Some men are more beholden to their bitterest enemies than to friends who appear to be sweetness itself. The former frequently tell the truth, but the latter never.

He that openly tells his friends all that he thinks of them, must expect that they will secretly tell his enemies much that they do not think of him.

He that has never known adversity, is but half acquainted with others, or with himself. Constant success shows us but one side of the world. for, as it surrounds us with friends, who will tell us only our merits, so it silences those enemies from whom alone we can learn our defects.

The reason why great men meet with so little pity or attachment in adversity, would seem to be this: the friends of a great man were made by his fortune, his enemies by himself, and revenge is a much more punctual paymaster than gratitude.

Beware of no man more than of yourself; we carry our worst enemies within us.

He who cannot agree with his enemies is controlled by them.

When we hate our enemies, we are giving them power over us: power over our sleep, our appetites, our blood pressure, our health, and our happiness. Our enemies would dance with joy if only they knew how they were worrying us, lacerating us, and getting even with us! Our hate is not hurting them at all, but our hate is turning our own days and nights into a hellish turmoil.

To be deceived by; our enemies or betrayed by our friends is insupportable; yet by ourselves are we often content to be so treated.

Never explain. Your friends do not need it and your enemies will not believe you anyway.

Never explain: your friends don’t require it, and your enemies won’t believe you anyway.

Our best friends and our worst enemies are our thoughts.
