The possible posting of Col. (res.) Shaul Kamisa as ambassador to Egypt could damage Israel-Egypt relations, according to an internal memo sent to Foreign Ministry director-general Yossi Gal on Sunday. Sources in the Foreign Ministry say the Egyptians will refuse to accept Kamisa because he is a political appointee close to Foreign Minister Avigdor Lieberman, who has had frosty relations with Cairo. The memo, which Haaretz has obtained, stated that Kamisa's military background and his active role in Yisrael Beiteinu will damage Israel, and that relations between Israel and Egypt are more important now than ever, hence the great importance of appointing a career diplomat as ambassador. The Egyptian Foreign Ministry in Cairo and the Egyptian Embassy in Tel Aviv declined to comment on the report of Kamisa's possible appointment, except to say that they had received no official word of it. "This might just be a trial balloon," an Egyptian diplomat told Haaretz. Senior Foreign Ministry officials said they believed that because Lieberman had appointed a person who is closely associated politically with him, the Egyptian authorities would be in no hurry to approve his credentials as ambassador.The reaction in this morning's papers in Cairo is predictably irate. One wonders whether this is Lieberman's way of getting back at Bibi for shutting him out of the important relationship with Egypt.
