When Israel was established, its tiny community of ultra-Orthodox Jews were, uniquely, exempted from the normal requirement of service in the Israeli Defence Force. They were seen as keepers of the spiritual soul of the nation, and their vital duty of studying religion and Jewish law was more important than wielding guns. 70 years on, and the community's numbers have grown massively - and there are increasing demands for the ultra-Orthodox to play their part in the defence of the nation. A Supreme Court decision which has cleared the way for the drafting of all Jewish citizens reaching the age of eighteen has divided the coalition government and led to furious rows.
