Final answer:
The U.S. should have gotten involved in World War I for reasons of self-defense, promoting democracy, and pursuing economic interests.
Step-by-step explanation:
The U.S. should have gotten involved in World War I because of the following reasons:
Self-defense and protection of its national interests: Document #1 states that Germany intended to help Mexico regain lost territories in the U.S., which posed a direct threat to U.S. security. This document shows that the U.S. had valid reasons to protect itself and its citizens.
Preserving democracy and promoting peace: Document #2 highlights how the U.S. viewed its involvement as a way to uphold democratic values and prevent future conflicts. The U.S. believed that its intervention would contribute to the establishment of a peaceful world order.
Economic interests and opportunities: Document #3 reveals the economic benefits the U.S. anticipated from its participation in the war. The U.S. saw the opportunity to expand its influence and increase trade, leading to economic growth and prosperity.
In conclusion, the evidence from these three documents demonstrates that the U.S. had legitimate reasons for getting involved in World War I, including self-defense, the promotion of democracy and peace, and economic interests.
