no-one is taken responsibility but al-al-shabab remains a security in the country >>> david sheahan is a professor of international relations and a former u.s. ambassador to burkina faso and ethiopia. >> the efforts haven't worked. it shows a weekness of the government of somalia. were it not for some 20,000 african union troops in somalia, the government probably could not withstand the pressures from al-shabab. but at the same time it demonstrates a certain weakness by al-shabab, even though they have increased their military capability in the last seven months, i don't believe they're able to hold over any extended period of time a sizeable city in somalia. they can pretty much travel wherever they wish in south central somalia in the rural areas, attack amazon outlying bases and even a major town. i don't believe they can hold them >>> interesting that you say things would be worse if it wasn't for the african union force that is there because if you talk to a lot of somalis, many of them would say that those troops are part of the problem and they are, in fact, making things worse
