Here’s what the note says according to the article:

"These ambassadors assert that our position in favor of Israel is misunderstood in the Middle East and that it breaks with our traditionally balanced position between Israelis and Palestinians. The note [relates] a loss of credibility and influence of France, and notes the poor image of our country in the Arab world. Then, in a rather diplomatic form, it suggests that all this is the result of the positions taken by the President of the Republic.

The crisis of trust between France and the Middle East is ‘serious’ and risks being ‘long-lasting’, warn the authors of the note. ‘We have experienced crises in the past with the caricatures of the Prophet Muhammad, but we were able to defuse them quite quickly,’ recalls the diplomat who read the note. ‘This time,’ he adds, echoing the warning of the dissenters, ‘the distrust towards us is deep and likely to last. Our interlocutors feel that we are betraying ourselves; they believe that our discourse based on humanism is in contradiction with our new approach. For them, France with its alternative voice no longer exists.’"
