Behr was often in Algeria, and in 1958 published "The Algerian Problem". The book had the virtue of being written by a French-speaking outsider with some understanding of, and sympathy for, the positions of both the French and the Algerians. Written when the war was far from over, and going back a century or more over the background, it was considered a fair assessment of a problem which many Frenchmen reckoned no foreigner could possibly understand. The book was said to be compulsory reading at the United States Department of State.
