in Yemen were experiencing high levels of acute food insecurity. Impact on health According to The Guardian, The blockade of Yemen by the Saudi-led coalition has caused medical supplies, food, and fuel to run low, doctors and aid organizations said. United States's role The U.S has supported the Arab coalition's intervention in the war and the United States Navy actively participated in the naval blockade at the beginning of the intervention. In mid-2015, Washington increased its logistical and intelligence support to Saudi Arabia by creating a joint coordination planning cell with the Saudi military to help manage the war. However, in mid-2016 and amid escalating, international concerns regarding some of the strategic initiatives undertaken by the Saudi Arabian military in the conflict, the U.S. pulled back significantly on their participation in this joint planning cell, reducing its staff commitment to only five US workers.

The U.S. dispatched warships in the region after Houthi missiles targeted the UAE-operated HSV-2 Swift, which some critics interpreted as the U.S. reinforcing the coalition blockade. According to Iranian sources, it has refueled Saudi planes, sent the Saudi military targeting intelligence, and resupplied them with tens of billions of dollars worth of bombs. U.S. President Trump asked Saudi Arabia to allow humanitarian aid to enter Yemen in 2017. The U.S. (and the UK) support the effort through arms sales and technical assistance. Amnesty International urged the U.S. and the UK to stop supplying arms to Saudi Arabia and to the Saudi-led coalition. It has been reported that U.S. is regarded as an indirect partner for Saudi Arabia in the war and blockade on Yemen.

The article states that Biden and Congress have taken no real action to end support for the coalition after declaring that he would end "all American support for offensive operations in the war in Yemen, including relevant arms sales." On earlier September 2019, a report of UN investigators team, commissioned by the United Nations Human Rights Council claimed that the US, Britain, and France, are probably complicit in the war in Yemen due to persisted sales of weaponry and intelligence
