A report by US-Africa Command (AFRICOM) says despite the Botswana government's significant achievements since 1966, Botswana's prosperity and political stability are more fragile than is frequently recognised. Dated June 2011, the report says three current realities form the core of this fragility: a population that is highly-dependent on social welfare programmes provided by the state; a state that is heavily reliant on a single commodity (diamonds) that is highly sensitive to fluctuations in the global economy; and a narrow economic base that leaves the country deeply tied to that of neighbouring South Africa.
