Hawiy thrives on anarchy and they will stay put in Lower shabelle.Lower Shabelle borders Banadirs they're right nex to one another. You're right that ain't many RX present on media like Darood Isaaq & Hawiye.
Hawiye are shooting themselves on the foot like you said because the more they land grab RX & other minorities territory the more they're increasingly pushed to the arms of Al Shabaab. LS is next to Mogadishu which is itself a major security threat to the entire Somali government and only strengthening Al Shabaab as majority of recruits are RX who will slip through to Mogadishu enforcing Al Shabaab capabilities preventing a real progress to end the civil war.
Hawiye must ask themselves if these prime farmlands are worth destabilizing Mogadishu and recurring suicide attacks, murder, extortions and all calamities brought upon by Al Shabaab.
