1) Allah swt didnt give them victory in the ramadans of 2006, 2007, 2008, 2009 and 2010. But why not? Are they not mujaahideen on the right path, the others are disbelievers or apostates? This backfired on themselves. Allah swt did give victory to xarakada hezbullah al mujaahidiin, does this mean the shias are better guided than shabaab?

2)Not only they failed, but also lost many key positions and towns such as degmada Hodan and Wardhiigleey, Beledxaawo, Garbahaarey, Luuq and Ceelwaaq
3) extreme famine destroyed their women and children, made them flee to Kenya. the eelays who are majority in alshabaab have been hit badly by this famine, thats why abu mansur allowed disbelievers to operate in baidoa. But here is the dilemma: amiir Abu Zubayr al-niqabi didnt allow that, so now there is huge conflict between him and abu mansur. May God increase their disagreement and turn it into violent one.
4) khilaaf between abu mansur and axmed godane
5) Drones joined the war
