According to The New York Times, the legal claims by hundreds of American survivors of Nazi death camps have set off an intense lobbying campaign in Washington on their behalf. But opposition from the government and even from leading Jewish groups has created an uncomfortable rift between groups that are normally in alliance and has created a potential minefield for President Obama. The State Department, under both the Obama and George W. Bush administrations, has vigorously opposed the idea of allowing survivors to press claims in court against European insurance companies because they say it would undermine a reparations agreement that the United States reached in 2000 with Germany, which led to $300 million in insurance payments to survivors and their heirs.
