An alliance made with the high and mighty can never be trusted.
This little fable proves my point.
A cow and a she-goat and a long-suffering sheep decided to become the lion’s companions. They went into the forest together and there they caught an extremely large stag which they divided into four portions. Then the lion said, ‘I claim the first portion by right of my title, since I am called the king; the second portion you will give me as your partner; then, because I am strongest, the third portion is mine … and woe betide anyone who dares to touch the fourth!’ In this way the wicked lion carried off all the spoils for himself.
