An anonymous writer from the revolutionary newsroom of Iran has attacked France where it hurts most -- right in la grandeur .

Simple criticism would have been easy to take. France did offer asylum to Ayatollah Ruhollah Khomeini before he took over Iran, but, after all, the United States and the Soviet Union are almost daily victims of Islamic wrath in the Tehran press. This is high-powered company and, as a great power, revolutionary diatribe is something you have to bear. Besides, who knows better than France that gratitude has no place in affairs of state?

However, to be called an "adolescent Satan" when Washington and Moscow are "great Satans" could be seen as a slight of France's role on the world stage.

That may be what the editorial writer at Tehran's Azadegan newspaper had in mind yesterday when he said: "The Moslem people of Iran must know that the danger of France and such adolescent Satans is no less than that represented by the aggressor U.S.S.R. and the bloodthirsty America."

His insult -- c'est le comble -- was relayed to the world by the French news agency, Agence France-Presse.

What the writer attacked specifically was France's authorization for former Iranian prime minister Shahpour Bakhtiar to live in Paris and the French government's friendly relations with Iraq and other Arab countries lined up against Iran.

For its ties to these countries, he said, France "is going to receive a lesson from Iranian Moslems that she is not likely to forget" -- a lesson the writer may already have given.
