A Tax Break Fuels Middle East Friction

For many years, the United States has had a policy against spending aid money to fund Israeli settlements in the West Bank, which successive administrations have regarded as an obstacle to peace. Yet private organizations in the United States continue to raise tax-exempt contributions for the very activities that the government opposes.

But critics of Israeli settlements question why American taxpayers are supporting indirectly, through the exempt contributions, a process that the government condemns. A search of IRS records identified 28 U.S. charitable groups that made a total of $33.4 million in tax-exempt contributions to settlements and related organizations between 2004 and 2007.
