In modern society, going into exile is no longer the norm. It is not easy to get success stories of governments in exile anymore. Exile is defined as a state of being barred from one’s native country, mainly for political reasons. This may include banishment and expatriation, or simply barring someone from their native country.
Self-exile such as the one NASA leader Raila Odinga is contemplating is normally taken as a form of protest to avoid persecution or legal battles on matters such as tax or crime. Some go into exile as an act of shame or repentance while others take the path to isolate themselves so they can devote their time to a particular course.
