It is such a sad thing that we can't go back in time and undo certain things. Honestly, Nigeria is supposed to be a great nation but our greed and differences gave way for others to use us and exploit us to the brim. The annoying part is we are still ignorant of this thing and the little resources we have are still been carried away.
Civil war is something I always wish I can undo, the effect of that event is something that we are still suffering from to date.
We all have a lot we wish to undo and civil war is one of it , the loopholes it creates are still there today.
