Rudyard Kipling had an answer to in his poem, Gods of the Copywrite Headings:

When the Cambrian measures were forming, They promised perpetual peace. They swore, if we gave them our weapons, that the wars of the tribes would cease. But when we disarmed They sold us and delivered us bound to our foe, And the Gods of the Copybook Headings said: "Stick to the Devil you know."

Obviously we aren’t learning the lesson, we keep repeating the same mistakes.
