You want do what???
With whose money and for what army?
The SNA is corrupt, incompetent and underfunded. The current administration can't pay the salaries of an already underpaid "army" and you want to buy fucking attack helicopters.
Get back to reality.
Why hasn't the civil war ended in Somalia by now?
Ever asked yourself that question?
With an arms embargo there will never be a dominant force that could consolidate all of Somalia.
Most wars quickly end as there'll be a winner.
However without weapons everyone will be on the same playing field and hence the war will continue forever.
SNA is corrupt because there was never a plan to liberate the south from Al Shabaab anyways.
FGS & AMISON are interested in keeping the status quo.
However if there were some decent weapons around then an enterprising general or warlord might decide to use those weapons to arm himself and attempt a coup.
The moment you have a single faction in Somalia able to foster enough force to scare the other warlords into submission is the day we get our country back.
I bet the moment they remove the arms embargo those warlords won't even bother to fight for it.
They'll be on the first flight to London or Buffalo NY with their ill-gotten gains.
