Though it is a question of socio political implications on religious issues in Nigeria.
Nigeria was colonized by British over the century and more Catholics, equally protestants and considerably other Christians are there.
Does Nigeria foreign policy allows new immigrants to be part of these religious groups?
How far the existing religious groups have obtained the benefits of foreign policy?
Is it favourable to get the privileges from the Government due to the rigid foreign policy issues?
The foreign policy has to be more citizen friendly to embrace all the citizens of different religious groups.
The main important point is to be highlighted here that the existing foreign policy could enhance the stakeholders objectives to fulfill the dream of further development.
This is quite a loaded question that may require a sizable research.
Having said that, religious crises in Nigeria can have socio-political implications for the country's foreign policy. They can harm Nigeria's reputation and damage its relationships with other countries, particularly those where religion plays a significant role.
Furthermore, such crises can lead to refugee situations and cross-border conflicts, which can have wider regional and international repercussions.
National consciousness remains vital for nation-building. Nigeria is a multi-ethnic, multi-religious, and multi-cultural state. This diversity was more emphasized by her colonizers and it was capitalized on as a tool for domination and exploitation. Sadly, what one finds now, after re-gaining her “independence” is the logic that enthrones this diversity. The major interest of individual groups tends more toward re-affirming tribal and ethnic identities, and politicians have continued to use this medium to promote their interests. Simply put (and sadly so), Nigeria lacks a national consciousness that is needed for nation-building, and unless religion is first understood as a unifying factor, policies will stay defective. Diversity is not a cause of division but a call for integration.
Two things: First, without dialogue and unity, internal policies will lack equity, fairness, and justice. The second is, on the global scale, relations with other countries are affected (migration, financial market, and the like), for it is almost impossible to invest in areas of conflict, without “gains.”
