For a long time，foreign aid has been an important means for the United States to safeguard national interests and achieve strategic goals. After the Iraq War，the core of the United States’ policy towards Iraq was reconstruction，and aid was the main means of serving reconstruction. In terms of the U.S. assistance to Iraq，implementing democratic transformation and enhancing anti-corruption governance capabilities in the political field；Give priority to supporting the oil industry and building a diversified economic structure in terms of economy；Restore public services and improve people’s livelihoods in the social sphere；Provide military assistance to the Iraqi security forces on a military level. The United States aid to Iraq has had little effect，and currently Iraq still faces many urgent problems such as political division has intensified，economic development has stalled and social unrest has continued. The reason for this is that，from the perspective of donor countries，the utilitarian and instrumental characteristics of aid determine that it only serves the national interests of the United States；from the perspective of recipient countries，the unique political and economic forms formed in Iraq’s history have played a role in dissipating US aid. Therefore，foreign aid must be based on the national conditions of the recipient country，adopting an aid model that is equal，mutually beneficial，pragmatic，and does not attach any political conditions
