Ethiopia–United States relations

The United States of America and the Federal Democratic Republic of Ethiopia diplomatic relations has gone through decades and through multiple regime changes and billions of dollars of support. Since a new Prime Minister has entered the U.S attitude towards Ethiopia has drastically changed. The U.S government during the TPLF supported the dictator regime and forgetting its human rights violations according to reports. 
TPLF Era relations.
Bush and Meles.
President Bush had a strong relationship with Meles Zenawi. He once claimed to have over 90 precent of the votes while millions disapproved his leadership. The Bush administration didn't care about Meles's abuses and the human rights violations nor tried to make Ethiopia a freer society but only diplomacy mattered for the horn of Africa and the Bush administrations interests.
Haile Mariam and Obama.
Barack Obama the 44th President of the United States visited Ethiopia as the first sitting U.S President ever to. But the visit included Obama's remarks on human rights. The President also mentioned the regime to be a democratically elected government which sparked outrage with most Ethiopians due to the fact the TPLF was by far opposite from a democratically elected government which later on caused a huge protest which caused the demise and downfall of the regime terrorist organization. Obama had stayed in the city for a 2-day state visit
Abiy Administration Era relations.
The U.S under the Abiy admin has had a negative U.S relations. It was from the start of receiving the Nobel Peace Prize when the President criticized Prime Minister Abiy Ahmed by being awarded the Prize which later Abiy responded and said the decisions were up to the Nobel committee and not him and he should have the problem with the Nobel committee. And 2020 the U.S president said it's a very dangerous situation because Egypt is not going to be able to live that way". Referring to the GERD Dam on the Blue Nile which originates from Ethiopia and under Ethiopian jurisdiction. The President also added and said Egypt will “blow up” the 5-billion-dollar dam. This sparked outrage and caused many to denounce it and even the Ethiopian government showed its huge disapproval. Later on, sanctions were being imposed on the country for not allowing Egypt to have the upper hand on the Grand Ethiopian Renaissance Dam Project on the Blue Nile, but later on these sanctions were moved away and Ethiopia was allowed getting the decades old aid again. 
Biden.
Under Joe Biden the U.S State Department designated Ethiopia as a not to travel level 4 country. This was due to civil unrest and armed conflicts which are mostly in the north and hundreds of miles outside of the capital Addis Ababa. The Abiy- Biden relation might be even worse as Biden accused Ethiopia in the UN General assembly. And multiple calls for cease fire in the worn torn north of the country but the government of Ethiopia saying they will not negotiate with terrorists. Biden in January the 11th made his first call with Prime Minister Abiy Ahmed and exchanged views on the war in the northern region of the country. People have also aligned Biden with supporting the TPLF a terrorist organization.
