It depends on your definition of "charity". If you're talking about Friends of the Israel Defense Forces, Wikipedia says:

>The organization states that it is the official U.S. charity authorized to collect donations for IDF soldiers.

>Charity evaluators have generally rated the organization favorably.[9]

>The organization is recognized as a tax-exempt 501(c)(3) charity in the United States and has been tax-exempt since July 1983.[2]
