1. Stop loaning them money.
2. Stop feeding them.
3. End all medical assistance (esp. for AIDS).
4. End all peacekeeping missions.
5. Seize all of their foreign assets (want a Liberian-registered freighter - cheap?)

Truth is, if they can't run their own countries, maybe they need their colonial masters back.
Of course, I don't think they could pay the UK, France, Belgium, Germany, etc. to come back. Maybe the PRC is willing to help?
And if they thought Westerners were bad, wait until they meant their Chinese taskmasters...

African countries don't need colonial "masters" back. They need to grow out of the tribalism that makes nation-state democracy so difficult. And before you write them off because of their tribalism, take a good look at the history of the various peoples of Europe, most of which had the same history of tribal infighting in their past. The United States didn't spring fully formed from the Roman Empire or the clans of Scotland. These things take time.
