What i would do to make Somalia prosper is this.
1- Abandon this stupid 4.5 system and this clan federalism , dissolve parliament and re-write the constitution.
2- Ban all warlords , corrupt officials and tribalist from running in any government whether it be local or federal.
3- A new federal government that would be elected by the people through elections and would have to go through tests to make sure they are capable of the role they would be taken . For example, if someone was to be chosen for the role of finance minster , they would have to have some high level form of education regarding public finance, I think the minimum should be a masters/Phd in economics or public finance or something that related to the role of finance minster. They would also have to go through tests relating to Somali history and the history of Somali governance and advance level tests relating to the field they would be taking in government to make sure those with fraudulent degrees could not take these positions. They also should appear before a group of MPs who would further question their stability for the role they were undertaking. This is is extended for the president and the prime minster as well. As for regular MPs , they should at least have a bachelors degree and pass the tests relating to Somali history and governance.
4- Adopt a new federalism model that focus on local governance so that people can improve their own small communities without relying on the federal government government. Federal states should be split along tribal lines but this would be different from the federalism we have now. They would have far less power , they would be unable to have armies , unable to engage in foreign affairs , their role would be to serve their local federal state nothing else. The elected federal government would tell them what to do , for example reduce child morality and they would do just that nothing more nothing less.
5- Create an independent corruption department , completely independent from local and federal government with the sole purpose on reducing corruption. They would enjoy special powers such as tracking officals spending , the ability to search homes etc. They would have a close relationship with the local and federal police forces to make sure corruption was zero.
6- Train a new multi-tribal armed forced which would be equally split between tribes so that one tribe does not have more member than another.
7- Tell Al-shabaab to either have peace talks and abandon their terrorist ways or be destroyed. The government should make concessions and promise they won't be tried or put in jail and once al shabaab surrenders and the government gains the power then arrest all ex shabaabs leaders and members and jail them. Their crimes will never be forgotten.
8- Set up a civil war tribunal with the purpose of finding those responsible of committing atrocities during the civil war and try them. For example general morgan , mahdi etc holding them accountable for their actions. The federal government should also take responsibility for the actions of the kacaan government and offer reparations to the victims of the actions committed by the government. They should also offer apologies , an apology goes a long way.
There is a whole lot more i can think of but i don't want to write an essay so here are just some of the things that should happen. Sry for the typos.
