Why not they are understand the current reality better than some old people who born under the dictatorship and wish things could back to those days (which is pure delusion). If anything we need a leader that has only lived under PL for most of their life, to serve the people they represent.
They understand the reality of Puntland and they also care most about the consequences of each decision made.
But if you are someone that has seen underdevelopment your whole life, wouldn't that underdevelopment be the optimum living conditions for yourself?
Do you think Diyaano has seen a world-class port or airport before?
In terms of development, men like Diyaano have only seen the current state of Somalia. They wouldn't know anything about free-trade zones, dual-carriageway roads, industrial parks etc. PL is currently reaching the point where it is ready for large foreign investment, it needs someone that understands the end result rather than thinking anything is a bonus.
Furthermore, Diyaano would not have the political acumen to deal with the certified jahiils in Xamar or Hargeisa, let alone the western educated civil service that the FGS aggressively recruits.
The only thing I can honestly see Diyaano being decent at, might be defence and public initiatives.
