I'm nearly 80 so I remember quite a lot and I don't agree with you .....
I don't know how you define "invade". The Arabs fought and won back Mauretania and Algeria from the French but those were Arab nations anyway, so "invade" doesn't sit well with my definition. The Arabs fought and won back the Spanish Sahara from Spain but again it was an Arab nation anyway so "invade" is an odd word to choose. The rest of the Maghreb was either fought over or released by diplomacy including Egypt, Tunisia, Libya, Sudan, and Yemen from France and Britain. Lebanon, Syria, and Jordan were also fought over and returned from France and Britain. We can discuss and even argue over which ones were "invaded" but the point is that the ONLY Arab nation that "lost" (that I can think of) is Palestine.
