Have Tunisian Arabian horses disappeared?

Back in the 1990s, when Hansi Heck-Melnyk and I were trying to account for all Tunisian horses in Tunisia and Europe, there seemed to be an inexhaustible supply of these beautiful, dry Arabians with lines that traced exclusively to horses imported from the desert of North Arabia. Tunisia was indeed had the one of the largest pools of such Arabians, after Egypt but before Syria (pre-civil war) and Bahrain. The Tunisian state stud of Sidi-Thabet which I visited in 2004 (or was it 2005?), was filled with good broodmares. Today, almost thirty years later, one is hard-pressed to find a horse with a 100% Tunisian pedigree. Most everything at the state stud of Sidi Thabet seems to have been top crossed with doubtful French blood. There may be a few left at Gisela Bergmann’s near Jendouba, and a couple others in private hands, but that’s about it in Tunisia. Maybe a few more in Germany (thanks to the Bergmann’s influence), and one or two old mares in France, but there hasn’t been any Tunisian stallions there in a while, the last one being Jassem (Koraich x Nefissa by Madani). How can that be? Can someone undertake a survey of what…
