Answer:
the United States declared war on Germany due to a combination of military, economic, and political factors, as well as public opinion.
Step-by-step explanation:
The United States declared war on Germany on April 6, 1917, during World War I. The United States had remained neutral for most of the war, but eventually entered the conflict due to a series of events and factors, including:
German submarine warfare: In 1917, Germany resumed its unrestricted submarine warfare campaign, sinking several American ships and killing several American citizens. The United States demanded that Germany stop these attacks, but Germany refused.
The Zimmermann Telegram: In January 1917, the British intercepted and decrypted a telegram sent by the German Foreign Minister, Arthur Zimmermann, to the Mexican government. The telegram offered German support for a Mexican attack on the United States in exchange for Mexican support for a German victory in the war. The United States was outraged by this offer and considered it an act of aggression.
American economic interests: The United States had significant economic interests in the outcome of the war, including loans and investments in the Allied powers (Britain, France, and Russia) and the desire to protect American businesses and trade.
American public opinion: By 1917, many Americans were strongly anti-German and favored entering the war on the side of the Allies. This sentiment was fueled by German submarine attacks, propaganda, and the Zimmermann Telegram.
Overall, the United States declared war on Germany due to a combination of military, economic, and political factors, as well as public opinion.
