Below we see Jeish al-Muhajireen wal-Ansar (JMA) shar’i “Abu Azzam al-Najdi’s” frank rationale for leaving JMA to join the Islamic State (IS / ISIS). Jeish al-Muhajireen wal-Ansar is a mostly foreign fighter battalion that has been active in Aleppo. It is best known for its Caucasian (e.g., Chechen) contingent, but it also counts Arabs among its ranks — it recently absorbed the heavily Saudi al-Katibah al-Khadra (the Green Battalion), and Abu Azzam’s nom du guerre indicates that he hails from the Najd (east Saudi Arabia). Abu Azzam had been JMA’s shar’i and, at least in Arabic media, its main fundraising point of contact. Saudi fundraiser and ideologue Abdullah al-Muheisini had recommended as late as April that any would-be foreign fighters should reach out specifically to Abu Azzam.
Abu Azzam defected to ISIS alongside a substantial chunk of al-Katibah al-Khadra, including its commander Omar Seif and at least one of its shar’is. (Seif had apparently just been detained by the Syrian Revolutionaries Front on suspicions, now vindicated, that he was linked to ISIS. Other jihadists intervened to broker his release.)
As can be seen below, there are a number of strains to Abu Azzam’s thinking, or at least what he’s willing to disclose of it. Some of it reads like picking a winner: on the one hand, an endorsement of ISIS’s success in building a functional Islamic state; on the other, disillusionment with the dysfunction of rebel-controlled areas and a clear distrust of non-jihadist rebels. The current U.S./Coalition campaign on ISIS apparently figures into his logic, too, pushing him to advocate jihadist solidarity with ISIS to better resist “the nations of disbelief.”
ISIS and pro-ISIS accounts have been crowing about successive jihadist defections to ISIS, doing everything they can to advertise ISIS’s continuing momentum. When it comes to drawing away foreign fighters, I suspect they’re right – Abu Azzam is not the first to defect to ISIS, and I doubt he’ll be the last.
