An enemy of yours is an enemy of mine; an enemy of mine is an enemy of yours; if an enemy of mine is not an enemy of yours, then you're an enemy of mine.

- John Yang aka Private83

The enemy of my enemy is my friend, men said, but the enemy of my friend is my enemy.

- George R.R. Martin, A Dance with Dragons

If you aren't destroying your enemies, it's because you have been conquered and assimilated, you do not even have an idea of who your enemies are. You have been brainwashed into believing you are your own enemy, and you are set against yourself. The enemy is laughing at you as you tear yourself to pieces. That is the most effective warfare an enemy can launch on his foes: confounding them.

- Bangambiki Habyarimana, Pearls Of Eternity

The enemy of my enemy is my friend.

- Dan Wells, Fragments

If the enemy of my enemy is my friend, then a friend of my enemy, is my enemy.

- Pyreglide

The enemy of my enemy is my friend.

- Arabic proverb

Your friends are three and your enemies are three. Your friends are: your friend, the friend of your friend, and the enemy of your enemy. Your enemies are: your enemy, the enemy of your friend, and the friend of your enemy.

- Hazrat Ali Ibn Abu-Talib A.S

In order to know your enemy, you must become your enemy.
