Isaak has only one reason to continue to livethe hope that he will be able to escape this totalitarian terror and rejoin his family. Sadly. Isaaks case is hardly unique. Nearly 400.000 Jews in the Soviet Union have been denied requests for exit visas. Millions more are afraid to apply or are otherwise suffering simply because they are Jews. We have seen in this century the ghastly consequences that can result when the world sits back and does nothing in the face of such religious and ethnic persecution. We who live in this land of freedom have a responsibility to act.
