No, they've only hated us since Jimmy Carter sold them out. That was after he sold out the Rhodesians. Or was it after he sold out the Americans in the Canal Zone but before he sold out the Rhodesians? He was selling out so many allies, it's hard to keep track. But I'm sure it was before he sold out the Republic of China.
They were most ARROGANT S.O.B.s you could ever meet. We Americans were DIRT beneath their feet.
What TICKED them off THE MOST was being mistaken for ARABS. Hahahahaha! How to annoy an Iranian to the nth degree: mistake him for an Arab.
Maybe they didn't HATE us, but they sure looked down their noses at us "inferior" beings.
