The UN issued a scathing report in 2016 stating that “[I]n particular, the legacy of colonial history, enslavement, racial subordination and segregation, racial terrorism and racial inequality in the US remains a serious challenge.” After international slave trade, abolition of slavery, Jim Crow laws, civil rights struggle, ongoing systemic police brutality against African Americans and a prison machinery with a high prison rate with African Americans inmates the question remains: has racial discrimination ever ended in the US? The rising strength of a white supremacist movement poses another significant threat to the national cohesion of different communities in the US. Moreover, it reveals the dormant white nationalism that has awakened in light of policies and rhetoric animated and nourished by leading politicians in the country. To this end, this paper will investigate the following question: what is the impact of the colonial past on the US and how did the UN respond to this past? Finally, what will be the role of the UN to enhance the US human rights infrastructure for African Americans and ameliorate their situation in light of rising white supremacism?
