The paper discusses the debacle of corruption plaguing nations of the world. In the paper efforts are made to examine the milestones that have been attained in the fight against corruption in Nigeria. The milestones attained are both within and outside. It is argued in the paper that countries of the world are confronted with corruption which retards national and global development consequent to social unrests. Clearly, corruption is a global problem that requires global effort and collaboration to tackle. Hence, to mitigate corruption cooperation of victim and destination countries is required. In Nigeria where corruption is systemic, endemic and pervasive the nation’s resources are looted and stashed away within and outside the country causing under-development and social unrest. Therefore, to engender socio-economic progress, peace and stability in Nigeria corruption must be fought. One of the campaign promises by the government of Muhammadu Buhari was the fight against corruption and on assuming office the government began fighting corruption within and outside the country using diverse approaches. Although corruption is fighting back in Nigeria, a lot of milestones have been attained in fighting it. The paper discussed the milestones that have been achieved in the fight against corruption in Nigeria by examining these milestones within and outside the country in the fight against corruption.
