2 consequences due U. S. involvement in World War I? And 2 ways that minorities were involved (either in the military or the homefront)?

The United States delayed entering the war.

Explanation:

The public in the United States but neither the government were interested in entering the war. Yet certain events have taken place because of which the United States had no choice. In this context, we can mention the sinking of American ships by Germany, which violated the United States' non-attack treaty. The second reason is the economy. Namely, America produced large quantities of weapons. Britain and France bought a huge amount of weapons, quadrupled their imports. Most of these weapons were taken on credit. As the war progressed, there was a possibility that the two countries would lose the war. In that case, they would not be able to repay the debt to the United States, so that is one reason for American involvement in the war.

When we talk about the involvement of other groups in the war, we can point out that many women were involved in the military industry in the production of weapons. Also, women served in the war as cooks and nurses. Other racial groups were also involved in the war, such as African Americans and the Native American population.
