Until they sealed off the Egyptain border last year, Chaim could have purchased a ticket to Egypt ostensibly as a tourist visiting the pyramids, paid a Bedouin $1000 to guide him across Sinai, daubed himself with shoe polish like Hikind, and literally walked scot-free in to Israel together with all the 100,000 Sudanese schvartzers! With his excellent Black imitation he could even have pretended to be an anorexic Black Israelite from Brooklyn, whom the idiotic Zahal soldiers always welcome with open arms.
From there he would have layed low near the Tel Aviv tachanah merkazit or Dimona (not in Kfar Tapuach or Jerusalem, where he would have been promptly massered upon by "brother Kahanists!) for several months, and eventually when he revealed himself, the DIBs would have had difficulty legally deporting him.
As it is, Chaim will not feel the Israeli Sun this side of the Geulah: what a disgrace & a loss to Israel!
