Kenya doesn't have the same negative reputation in Somalia Ethiopia has (which is putting it very mildly, Ethiopia is probably about as popular in Somalia as Saddam Hussein was in Iraqi Kurdistan...)
Even so, I would be surprised if this alone would be enough for Kenya to succeed where Italy, Britain, the United States, the United Nations, and Ethiopia have failed, not to mention various domestic warlords who have tried to reunite the country.
Italy and Britain dealt quite easy with the Somalis, the Italian was only thrown out because the British invade, while the British left because Somalia was worthless, not because they were thrown out, as for USA and UN they never tried seriously to keep peace there. as for the Ethiopian invasion it had a limit goal which it reached (keep Somalia in chaos). In fact Somalia isn't Afghanistan, the area is relative easy to conquer and hold, if the invaders has the resources and are willing to sacrifice the necessary number of soldiers. As for such Kenya is both richer than Ethiopia and they have a interest in a peaceful and stable Somalia.
