Man, you need to read up on the battle of Isandlwana, where 20,000 Zulu warriors defeated (killed) 18,000 armed British troops. They had only assigai spears and ox-hide shields. Present-day brigands can break into armories and steal weapons, overpower local forces and take their weapons, and traffic with black-market troublemakers (no shortage in Africa) to obtain weapons from Angola and Mozambique. They attack unarmed civilians and "necklace" them. Tires and petrol...and a match. Even otherwise peace-loving Zambia had roving gangs of armed factions up to the last election. You sound like Lieutenant Colonel George Armstrong Custer: "These natives will be a pushover." History is against you.

All this didn't stop Robert Mugabe from imposing a reign of terror and driving out the white farmers from Zimbabwe, plunging the nation into starvation and penury.

What gives you the idea that any passage of time will solve a nation's problems? We've been around for ~250 years and, boy, do we have problems!
