I'd be surprised, as Lybia, the main theatre of war, was an Italian colony and the Germans did not stay long enough in Egypt, which by then was an independent kingdom anyway, although a protectorate. Tunisia was a French colony.
Sometimes one has to look from a different angle to what one reads to see whether it is propaganda or not.
And in Egypt the population is concentrated in the Nile Valley and Delta, all the rest is the Western Desert and by Desert they mean desert. So not too many malcontents there except for the odd bedouin who will say whatever you want to hear provided he has anything to gain by it. (This is my cynical streak speaking.
