Though it's still one of, if not the largest economy in Africa, Nigeria has had corruption and security problems for decades. The gangs, as well as Islamic insurgents, have reigned free as Buhari's elitist government has put oil industry corruption over the safety of its people. The political class needs to acknowledge its ever-growing failures and work with the likes of the US and the African Union to implement concrete economic and security measures.
The problem in Nigeria doesn't require more military spending or outside involvement but understanding where the budget money goes. After billions of dollars are spent each year, soldiers still complain about low pay and insufficient weaponry, leading to low morale among those fighting the gangs and insurgents. If the government can account for the money it spends on security, it would be able to rid its ranks of fraud and actually start protecting its people.
