Well Dino The Jews and Israel should only depend on themselves to protect their existance. Switzerland in particular has no good trackreckord in taking care of Jews. During WW II they handed Jews over to the Germans and in a real crisis they wouldn't care about Israel and the Jews again. Any advise from their side must be seen in that context.
