George H.W. Bush and Yitzhak Shamir (U.S. - Israel)
Margaret Thatcher and Menachem Begin (U.K. -Israel)
Margaret Thatcher and Yitzhak Shamir (U.K. - Israel)
Are some other ones. H.W.'s ties to Arab Oil was always going to make him an awkward ally to a right-wing government in Israel.
Same goes for Thatcher's relations with two founding members of anti-British Jewish Militias (Irgun and Lehi) during the Mandate period.
Not sure Bush and Shamir had such a bad personal relationship but rather the State dept. hated his guts. I doubt Thatcher really cared for Begin or Shamir (if she even met the later) but Shamir wasn't a very likable character as it is. Sharon dislike Chiraq and Begin dislike Mitterrand as he was best buds with Peres.
