But the civil war between the Government of Federal Democratic Republic of Ethiopia (GFDRE) and the Tigray Peoples’ Liberation Front (TPLF) endangered Ethiopia by complicating and threatening the territorial integrity of Ethiopia and imbalance the national interests between the USA and Ethiopia. The National interest protectors’ of Ethiopia passed through security dilemma and politics of undermined and disrespected relations within the internationalization of internal war that affect the bilateral relations between Ethiopia and the USA. This study basically uses the internalization of the fertile ground of the determinants of USA’s responses towards the civil war of Ethiopia in National Regional State of Tigray (NRST) in the constructivist view by qualitatively explorative research method that contains external factors. A study fills the gap of limited research work in issues and in number using scattered and inconsistent data. As a result, to accomplish American interests, USA responses during the first round of the war tended to incline to the TPLF to return the TPLF-led leadership by dominant shuttle diplomacy in Ethiopia, at the Horn of Africa politics and entire world politics like in the UN. Significantly during the war, the USA declined its assistance and made illegible Ethiopia by more than forty percent and from the African Growth and Opportunity Act (AGOA). At the end of the two years’ war, the USA succeeded in support of the permanent ceasefire of the Pretoria Agreement between war actors of GFDRE and TPLF led by AU. As a recommendation, the agreement for no war efforts must be expanded to continue the inclusive policy of acts in a way that will fulfill the strategic interests of the United States, Ethiopia, and Africa.en-USInternationalization of internal war, Civil war, Externalization, Internalization, Horn of Africa, Security Dilemma, and Diaspora diplomacyThe USA Responses Towards the Civil War of Ethiopia in Tigray National Regional StateThesis
