Final answer:
The US did not immediately declare war against Germany after the sinking of the "Arabic" in 1915.
Explanation:
False
It is false that the US immediately declared war against Germany after the "Arabic" was attacked by German U-boats in 1915. While the sinking of the Lusitania in 1915 did influence American sentiment, the US did not enter World War I until 1917. The decision to declare war was primarily driven by Germany's resumption of unrestricted submarine warfare and the Zimmerman Telegram.
