Once I met a guy at a wedding invitation and he graduated from one of the Middle-eastern university and then pursued a course in South Africa. He came across a book written by an Orientalist who theorised that any political organisation formed with the connivance of the colonialist power in order to succeed them would only have a life span of half a century. It was deliberately designed as such, probably to allow a “renaissance” from other parties to bring in fresh blood to the independent country.
From examples in India and Pakistan this prediction has been fulfilled with the demise of the Old Congress Party. Most likely we shall see the same fate here.
