There's not much solidarity between berber tribes..I can tell from the ones in morocco, a berber in north morocco will even rarely feel connected to the berbertribes in south morocco. Besides I'm not even sure if there're that many berbers in the mountainous parts of north africa(maybe with the exception of libyans and algerians; this b/c a fair share of the tuaregs reside in those countries) who know of the existence of tuaregs
