Explanation:
The U.S. entered World War I because Germany embarked on a deadly gamble.
Germany sank many American merchant ships around the British Isles which prompted the American entry into the war.
Rochester political scientist Hein Goemans answers the question why Germany was willing to risk American entry into the war.
Woodrow Wilson did not want war.
When World War I erupted in Europe in 1914, the 28th U.S. president pledged neutrality, in sync with prevailing American public opinion.
But while Wilson tried to avoid war for the next three years, favoring instead a negotiated collective approach to international stability, he was rapidly running out of options. Tensions heightened as Germany tried to isolate Britain in 1915 and announced unrestricted attacks against all ships that entered the war zone
