With the end of World War II, the United States of America, with the aim of developing its national security, took a new strategy to develop its economic, cultural and social influence in the world by shaping the governance structures of countries. In later years, this strategy became known as "nation building". The United States is the oldest and most experienced country in using this strategy to influence different countries, especially Muslim countries, and examples of its implementation can be seen mainly in Kuwait, Somalia, Haiti, Bosnia, Kosovo, and Afghanistan
One of the important countries in the Middle East region where the United States implemented its strategies was Iraq. Iraq's experience can be considered as the newest American nation-building project in the region and even the world. The US Department of State is responsible for the implementation of this project in Iraq, which seeks to protect the interests of the United States by using its executive institutions in this country. The United States Agency for International Development is the main pillar of the implementation of the United States programs in Iraq, and it pursues the nation-building strategy in Iraq by using the capital and experience of American foundations, institutions, and companies. The most important western institutions partnering USAID in Iraq are:
