Sixty years after the end of World War II, Jewish organizations are making what they are calling a last-ditch effort to track down Nazi war criminals in Germany before they and their victims die of old age. The initiative is sponsored by the Simon Wiesenthal Center in Jerusalem, named for the Nazi hunter who brought the infamous German war criminal Adolf Eichmann to justice. The campaign follows similar projects in the Baltic states in 2002 and others last year in Austria, Romania, Croatia, and Hungary.
