Every country has its problems. However, these countries are fighting and backstabbing for control...the major reason for the recent conflict is the fact that Ethiopia no longer has a border along the Red Sea and therefore relies on going through other countries such as Eritrea in order to ship and trade goods along that line.
Furthermore, Ethiopia and Eritrea have been accused of gross human rights violations. For example, Amnesty International points out that in Ethiopia, a large number of Eritreans are being detained just due to their Eritrean origins and that use of child soldiers on the front lines continue.
While, these wars are continuing both country's governments have been accused of starving the people and continuing war efforts instead of helping the welfare of the country.
