It's not only most Israelis, led by Prime Minister Benjamin Netanyahu, and the policy-community hawks in Washington and acolytes of AIPAC in the Congress who hate the interim nuclear agreement signed by Iran in November with the United Nations Security Council "P5-plus-one."
So do the leaders of the paramilitary Basij force in Iran and other Iranians who support a hard and hostile line toward the Great Satan and the U.N. diplomats who collaborated in setting up what many in the West, and no doubt in Iran, hope will prove a first step in reconciliation between the Iranians and the Western community.
Why do Americans hate the Iranians? Most Americans probably do not. It's the American government that has a grudge against Iran. That's because the American government was made a fool of in its dealings with Iran. And the U.S. government nurses grudges. (Think of Fidel Castro.)
