David Ignatius writes about a tax-exemption that should end:

There's nothing illegal about the charitable contributions to pro-settlement organizations, which are documented in filings with the Internal Revenue Service. They're similar to tax-exempt donations made to thousands of foreign organizations around the world through groups that are often described as "American friends of" the recipient.

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.

These donors should know that they are actually undermining the cause of Zionism by encouraging the bad behavior of the most self-destructive segment of Israeli society.
