They are 'illegal aliens' because their just entering the land and populating it without anyone permission. There is a government in Puntland, either follow the rules or laws and register yourself or leave, we will not be swallowed up by illegal aliens, we have other difficulties to deal with.
This will be great as we can keep track of their numbers before it becomes 'unfeasible' and we can begin deporting them back to their home-lands, at least by then they would've developed assets and money to go home. I know what the sneaky oromo is doing, it's similar to what the indians do in dubai. Take the local money and re-invest it into oromiya. It's what all 'large' populations do usually. Chinese, Indians, or anyone with a large population in relation to it's neighbors.
Do you think India and China rose up because of themselves? they use their people power to flood the world market and take jobs and then those indians invest in india. Indians and Chinese are half the world population, so if they use their people power they take half the worlds job. Its simple.
