You must bored and decided ''hey let me post some paranoia based nonsense.''
The ones going to Somalia are poor migrants, desperate ones at that. They have no power to conquer anything. They do the jobs somalis themselves look down upon. oromos leave out of desperation to make $$, if the govt of ethiopia did its job and created jobs and developed the country, you wouldn't see any oromos in somalia proper. This would be like White Americans saying ''omg so many somalis are in minnesota and in clarkston/stone mountain, georgia, they must be trying to expand and take our lands.''
as far as expansion, there is no way we'd get all the way to the border with somalia. besides some disputed lands on our border with somalis, there is no disputed lands deep within somali lands, or somalia proper/near the border with somalia.
