Why did Netanyahu himself have to appeal to Rumania and Bulgaria instead of using his Foreign Minister Lieberman for the job? These countries were in the Soviet block. Would they not talk to Lieberman? Do they also identify him as a former oppressor? Perhaps this is the reason. Another possibility: Lieberman is unable to "beg", in the same way that he cannot "apologize" to the Turks. Some mental limitation of a Soviet-educated man.
