I wanted to make sure that this is correct. Please give me your input. Thanks a lot!!

The countries involved in World War I was Russia, France, Italy, and Britain, Germany, Austria-Hungary, the Ottoman Empire, and Bulgaria. I think Mexico was also but not sure.

Germany’s actions were causing the U.S. to become aggravated and disturbed. Two main factors that led the U.S. to be involved in the war were discovering the alliance between Mexico and Germany. (Why did the U.S. become angry?)Between February 3 and March 21 German-boats sank six American merchant ships without warning. In April 2, 1917 declared war on Germany.

How did the U.S. decide which side to join in world war I?

In order to understand how the U.S. decided which side to join in World War I, you can start by researching the events and factors that influenced their decision. Here are some steps you can take to find the information you need:

1. Read about the events leading up to World War I and the initial alliances formed. This will help you understand why certain countries were involved in the war, including Russia, France, Italy, Britain, Germany, Austria-Hungary, the Ottoman Empire, and Bulgaria.

2. Look into the actions taken by Germany that caused the U.S. to become aggravated and disturbed. This might involve researching events such as the sinking of American merchant ships by German U-boats.

3. Investigate the alliance between Mexico and Germany. Find out how this alliance was discovered and why it may have influenced the U.S. to become angry. Look for information about any potential threats or concerns that the U.S. had regarding this alliance.

4. Learn about the specific events or incidents that led the U.S. to ultimately declare war on Germany. Look for the date and reasons behind the U.S. declaration of war.

5. Analyze all the gathered information and consider how these factors influenced the U.S.'s decision to join a side in World War I.

By following these steps and conducting some research, you will be able to understand why the U.S. decided to join the war and which side they chose to support. Remember to critically analyze the information you find, cross-reference multiple sources, and form your own conclusions based on the evidence presented.
