Answer and Explanation:
African countries have been extremely exploited and devalued by European nations and other nations considered to be world potentials. This exploitation has enabled African nations to become small, poor and often unskilled, which increases not only their problems, but also their devaluation around the world. Civilian governments have not been effective in solving these problems, which shows us that these governments are a flawed investment with no positive results, which need to be quickly changed by disciplined, rigid and imposing military governments, capable of bringing about real national changes.
