Mr. Hannity: Although Shah Pahlavi "led an often oppressive regime...our alliance [with him was]...strategically crucial". (p. 89)

My response: Here we observe two related ideas: the law of the balance of power and the principle of the lesser of two evils. Thruout history, nations have tended to collect into various loose federations in order to increase their security against an aggressive nation or to balance out one another's power. Through such politics, nations strove to preserve international harmony and to correct disharmonies and divisions. The principle of the lesser of two evils holds that a state party can side with a second state party which is generating or promoting certain evils for the purpose of mutually counteracting a third state party which is generating or promoting even worse evils.
