Israeli nukes are paid for by tax-exempt donations in the U.S.

"The U.S. Defense Department is so far refusing to produce a report that discusses nuclear technology issues in Israel, in response to a researcher's request for information." "The United States approved the sale of powerful computers that could boost Israel's well-known but officially secret A-bomb and missile programs," said the Risk Report article. "A 1987 Pentagon-sponsored study found that Technion University, one of the schools in the network, was helping design Israel's nuclear re-entry vehicle. U.S. officials say Technion's physicists also worked in Israel's secret weapon complex at Dimona." "In his complaint, Smith noted that the Weizmann Institute, Technion, and Hebrew University raise large sums of tax-exempt donations through affiliates in the United States. The American Society for Technion-Israel Institute for Technology Inc., for example, reported raising more than $65 million in tax-exempt contributions in 2011. According to publicly available tax filings by non-profits, the American Committee for the Weizmann Institute of Science reported $59 million in tax-exempt contributions in 2012, and American Friends of Hebrew University raised nearly $48 million in that same year. Smith's complaint noted that those substantial sums are sent to Israel in addition to the $86 billion in direct foreign aid Israel has received from U.S. taxpayers since 1987 when the Pentagon report was written."
