"As a teenager, Lieberman worked as a nightclub bouncer in Moldavia". Come on! Nightclub in the Soviet Union? You are kidding. There were four or five restaurants in Kishinev at that time with closing time 11 pm. He worked short time at nightclub in Beer Sheva after coming in Israel. Then as a worker at Lod Airport. By the way in Kishinev, Moldavia Lieberman was a student of Agricultural institute (now Agricultural university). See Russian Wikipedia.
