Final answer:
German U-boat attacks did not directly force the U.S. to declare war in WWI.
Explanation:
False: German U-boat attacks did not directly force the United States to declare war on Germany in World War I. While the sinking of the Lusitania and the resumption of unrestricted submarine warfare played a role, it was actually a combination of factors such as the Zimmerman Telegram and Germany's declaration of unrestricted submarine warfare that led to the U.S. declaration of war on Germany in 1917.
