The fate of many third world countries, especially those in Africa, would improve a great deal if they could unite in political federations. Yet many of these third world countries seem to find it hard to unite for their common good, especially when uniting means coming together to form real political federations. In fact, the trend seems to be toward further disintegration, as opposed to federation.
The first reason as to why third world countries find it hard to unite for common good is because majority of these countries are client states. As such, their patrons won’t allow them to form federations, for fear of losing the power they hold over them. You have to appreciate that the leaders of most of these client states are simply agents of the patron states: who get instructions for pretty much everything from the patrons.
The second reason as to why third world countries find it hard to unite for common good is because their leaders are afraid of losing power. So they’d rather hold onto the nominal power that comes from leading failed, unviable states, as opposed to federating for the good of their people. Of course, some states have genuine concerns of ending up being federated with other ‘evil’ states.
