Actually it is compulsory to fight against Hebellands but Xaarmajo is F dumb. He should deal first with Alshabab.
Even Americans are astonished by his stupidity. They say: Wtf dude, shabab is killing ur soldiers yet u focuss on other things?!
Al shabab is an elusive enemy. The Americans should be the first ones to know just how challenging it is to fight an enemy constantly on the move.
