At the January 26, 2016 meeting of the UN Security Council, Secretary General Ban Ki-moon justified the wave of stabbing, shooting, and car ramming terrorist attacks against Israelis as just "human nature."
In the words of the Secretary General:
"Palestinian frustration is growing under the weight of a half century of occupation and the paralysis of the peace process... Yet, as oppressed peoples have demonstrated throughout the ages, it is human nature to react to occupation, which often serves as a potent incubator of hate and extremism."
