Frustrated by U.S. reluctance to guarantee $10 billion in loans to resettle Jewish immigrants from the former Soviet Union, Israel is now asking Germany for some $6 billion in guarantees. So far, the Germans have brushed off the request. But Chancellor Helmut Kohl is under pressure to be more flexible. If Israel can't finance jobs and housing for incoming Jews, they could head instead for Germany, which worries about being overwhelmed by refugees from the East. More than 7,236 Soviet Jews came to Germany from June, 1990, to November, 1991. An additional 25,385 have applied for visas, and tens of thousands more have asked for application forms.
