A book on and Goodluck Jonathan / Sambo presidency in Nigeria. There are twelve chapters overall, interestingly in the title chapter and final chapter, Osai and Adesanya-Davies subject the Jonathan and Sambo presidency to a critical analysis regarding its capacity and proven efforts so far to achieve the much-desired cohesion and development in Nigeria. It is common knowledge that subsumed in the word 'cohesion' are peace and harmony; It is also common knowledge that, given the multi-ethnic content and a history of nagging worrisomely interethnic squabbles, interethnic relations in Nigeria ugly degenerated to a thirty-month civil war, which ended nearly the corporate existence of the nation as currently constituted. While peace and harmony require all hands to be on deck to be achieved, it is obvious that the burden of generating this social setting requires the commitment of government by way of public policies and programs that have the capacity of engendering peace and harmony. Here, the editors take a critical look at the Jonathan and Sambo presidency as an instrument of development. Recommendations are, thereafter, offered for consideration of the presidency with summary.
