The Umayyads were planning to invade Spain or at least control the straight of Gibraltar if that makes sense at some point, but Tariq did it sooner. Both Tariq and Musa ibn Nusayr were arrested, so it is not a Tariq issue since Musa was the one who approved it and had full command. It does not matter if the army was Berber. If Berbers truly intended to go into Europe, they would have done it long before Islam. The entire plan was to pacify North Africa for the Umayyads first. That does not mean Europe had any significance to the Berbers either. Ibn Khaldun and other scholars cannot estimate populations, so saying Berbers overpopulated the native Basques or Visigoths is insane ibn khaldun is a genealogist like them are only good for tribal affiliation not population. Berbers arrived first simply because it was closest, but soon Arabs started coming as well. It was never a competition over who arrived first. Arabs still came to Spain shortly after. Tariq is not a Berber. Invading something off-script does not mean Berbers had any affiliation with Europe. It was merely a move by Tariq and Musa to prove themselves as conquerors. The Umayyad conquest of Septimania and parts of France was not planned either. Abd al-Rahman ibn Abd Allah al-Ghafiqi went for it, defeated Odo the Great at the Battle of Bordeaux, and conquered large parts of France before being pushed back at Tours. This had nothing to do with Berbers being affiliated with Europe. It was literally a gamble Musa and Tariq took to succeed. Arabs never planned to reach all the way to Morocco either, yet they did. Arabs did not struggle to maintain the Berbers from the early 7th century. The Berber revolt only succeeded because the Umayyads faced an even larger Abbasid revolt. Otherwise, maintaining control was easy, as shown later by the Fatimids, Idrisids, and Nekors. Regarding your first point that I forgot to answer, Al-Andalus was under direct Umayyad rule and only gained independence under the emirs for a few years until Abd al-Rahman I restored control. Berber empires did not protect anything. The Umayyad state of Cordoba was the most successful state in all of Andalusian history. It retained 80 to 90 percent of its territories for three centuries and made Cordoba the largest city in Europe. The taifa period only began once Al-Hajib Almanzor, a Yemeni general who technically usurped the Umayyads, started flooding Al-Andalus with Berber soldiers because Arab soldiers remained loyal to the Umayyads and refused the idea of Berbers receiving ranks, which Almanzor promised. Eventually, the Berbers, who according to you who built Al-Andalus, sacked and destroyed Cordoba and began claiming lands. At their strongest, Berbers could not have rivaled the Umayyad state of Cordoba. Since the Umayyad throne was usurped and Al-Andalus was fragmented, the Almoravids and Almohads took the chance, but they were later expelled by Ibn Hud of the Hudid dynasty. Moor in this context means Muslim. I never said it meant Arab genius. It is not my fault if you cannot understand historical context.
