Among the reasons advanced, I agree with this one as I have shared before:

Gadhafi opens up a new Counter-offensive with Tuareg sympathizers against The New Libya Republic and NATO in order to reclaim his dictatorship over the people of Libya.

This therefore reaffirms and supports the other reason advanced in this article:

1. That Gadhafi's Tuareg army officers return to continue their secessionist war in North Mali. Gadhafi and the Tuareg secessionist movement have had a symbiotic relationship for decades. Ibrahim Ag Bahanga enjoys an unconditional safe haven in Southwest Libya where he escapes to, whenever his militia is overrun. The Mali Government and military has no appetite to cleanse North Mali of the secessionist militia because they form a significant part of the North Mali army contingent. Gadhafi has invested (Through Laico) a strategic amount of Libya funds in North Mali and in the secessionist militia for just such an eventuality. It is significant to note that the Tuareg people migrated from Libya, Algeria, and Mauritania southward into Mali, Niger, Tchad and The Soudan. They were the footsoldiers for Islam during the colonization of Africans via Islam, before the colonization via Christianity. Gadhafi has always been stuck in the past even as he feigned/faked leadership of Libya. To him, Libya was just a cash cow for the real tribes of the region, the berbers among whom the Gadhaafaa feature prominently. Therefore, a reconstituted Tuareg Secessionist movement in North Mali, IS NECESSARILY, Gadhafi's counter-revolutionary militia. The governments of Mali, Niger, and Tchad must not allow their nations to be used as staging ground for an untenable secessionist struggle against the peoples of Libya and Algeria. If they allow that, It will come back full circle because instead of an indigenous peoples' quest for justice, it is a moribund empirical and colonization war waged by hapless desert tribe and evangelists.

2. The second reason advanced in the article below is that, because Gadhafi's regime in Tripoli and Sirte had fallen and for his militias and mercenaries, it becomes each one save his own hyde. The loot in weapons are to be sold to Al Qaa'Ida of the Maghreb (AQMI) to support their resettlement efforts in North Mali and Niger.
To this reason I suggest the following:

 That AQMI is none other than the Tuareg secessionist militia, armed and sustained by the PROXY Gadhafi government of Tripoli and Sirte. As AQMI loses its value as crusading army, those regimes that propped it up are coming crumbling down with it. Therefore the idea that AQMI is some separate entity from Gadhafi and his Tuareg tribal militias is the biggest conard I've ever heard. In effect, the fall of the Gadhafi PROXY government of Tripoli and Sirte was the last nail in AQMI's coffin, having lost the battle against the people of Algeria, Tunisia, Misera, and the Soudan (Independence of South Soudan). There is only one reason AQMI would be based in the Maghreb and Sahara deserts. To destabilize the black African governments to the south and establish puppet governments to advance the re-colonization of the tribes of Africa via odious religion. If you do not agree with this reason for AQMI, you give us a good reason for AQMI's presence!!!!!!!!!!!!!!

My advice to the Tuareg tribes of Southern Morocco, Algeria, Libya, and Misera is the following:

Form, from among your number, political parties and join the conversation for governance with your sister tribes and clans and safeguard your rights and privileges in your nations. Work with your sister tribes of these nations to construct a viable society and invest in the growth and development of your communities. You are aware that all these nations are undergoing transformational changes (involuntary in Tunis and Misera, and voluntary in Morocco and Jazair). These transformational changes are divinely inspired and you have a significant part to play in them to reintegrate in your vrai societies. Your cultures of enslaving black Africans and the idea of marauding desert armies to colonize newer peoples and lands (via Islamic lore and religion) is unsustainable and unacceptable. If you can't abide by anti-slavery laws and work with your host tribes in these lands, you must pack up your shit and your camels and GIT. You are not welcome among these tribes. You have proven yourselves to be ungrateful guests. Libya has a lot of desert but has been endowed with abundant mineral resources in order that you can harness those resources and make life in a desert conducive to your cultures and traditions. There is a reason a desert separates you from the more genteel tribes you prey on to your south. Just as colonization of Libya by Europeans (Italians, French, British, Spaniards, Turks, Greeks) is untenable and unacceptable, so is colonization of Mali, Niger, and Tchad by the forlorn tribes of Libya, Algeria, Misera, and Tunis. So help me God. The clueless AU can go to hell. Haruna.
