I have heard mention of Memri lately, a group whose purpose, according to its website, is to bridge the language gap between the west - where few speak Arabic - and the Middle East, by "providing timely translations of Arabic, Farsi, and Hebrew media".
I suspect it's too good to be true. Their choices of articles are highly selective, and almost always chosen to make Arabs and Muslims look as bad as possible. They have almost no information on their web site about who they are, but Brian Whitaker, a Guardian columnist, used search engine archives to view old pages.
Its work is subsidised by US taxpayers because as an "independent, non-partisan, non-profit" organisation, it has tax-deductible status under American law.
Evidence from Memri's website also casts doubt on its non-partisan status. Besides supporting liberal democracy, civil society, and the free market, the institute also emphasises "the continuing relevance of Zionism to the Jewish people and to the state of Israel".
That is what its website used to say, but the words about Zionism have now been deleted. The original page, however, can still be found in internet archives.
The reason for Memri's air of secrecy becomes clearer when we look at the people behind it. The co-founder and president of Memri, and the registered owner of its website, is an Israeli called Yigal Carmon.
Mr - or rather, Colonel - Carmon spent 22 years in Israeli military intelligence and later served as counter-terrorism adviser to two Israeli prime ministers, Yitzhak Shamir and Yitzhak Rabin.
Retrieving another now-deleted page from the archives of Memri's website also throws up a list of its staff. Of the six people named, three - including Col Carmon - are described as having worked for Israeli intelligence.
Col Carmon's co-founder at Memri is Meyrav Wurmser, who is also director of the centre for Middle East policy at the Indianapolis-based Hudson Institute, which bills itself as "America's premier source of applied research on enduring policy challenges".
The ubiquitous Richard Perle, chairman of the Pentagon's defence policy board, recently joined Hudson's board of trustees.
Ms Wurmser is the author of an academic paper entitled Can Israel Survive Post-Zionism? in which she argues that leftwing Israeli intellectuals pose "more than a passing threat" to the state of Israel, undermining its soul and reducing its will for self-defence.
