'Selective Memri'

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".

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

It's a campaign that the Israeli government and American neo-conservatives have been pushing since early this year - one aspect of which was the bizarre anti-Saudi briefing at the Pentagon, hosted last month by Richard Perle.

To anyone who reads Arabic newspapers regularly, it should be obvious that the items highlighted by Memri are those that suit its agenda and are not representative of the newspapers' content as a whole.

The danger is that many of the senators, congressmen and "opinion formers" who don't read Arabic but receive Memri's emails may get the idea that these extreme examples are not only truly representative but also reflect the policies of Arab governments

Unfortunately, it is on the basis of such sweeping generalisations that much of American foreign policy is built these days.

As far as relations between the west and the Arab world are concerned, language is a barrier that perpetuates ignorance and can easily foster misunderstanding
