Unrestrictive sinkings (sinking without a warning).

"Unrestricted Submarine Warfare" was the policy followed by the German Navy to have German submarines without warning sink ships that were transporting food and other resources. U-boat was a term in WW1 referring to a submarine.
Dependable enough to sink large vessels (RMS Lusitania, e.g.), merchant ships and warships. Though ranges and armament were limited, the success of the German submarine fleet led to the Versailles Treaty having a condition that all German submarines were to be handed over to the Allies after the war. This was primarily so that the Allies could study German submarine technology in greater detail. The Germans were so far advanced in submarine technology that even their WWII technology legacy is incorporated into today's submarines (e.g., hull shape and design). Only the change in policy toward unrestricted submarine warfare kept the Germans from achieving more significant victories against enemy shipping and warships. Had they continued their initial policy, WWI may have turned out very differently.
After the German attack on the USS Greer on September 4, 1941, which was the first U.S. Navy ship attacked by a U-boat during World War II, President Franklin D. Roosevelt and the U.S. government took a firmer stance against German aggression. The incident led to increased naval patrols in the Atlantic and a more aggressive policy toward German submarines. Roosevelt famously declared that the U.S. would "shoot on sight" at German vessels, marking a significant escalation in U.S. involvement in the conflict prior to its formal entry into the war after the attack on Pearl Harbor.
For the US, what sped up its entry into World War One was the German declaration that unrestricted submarine warfare was going to begin again. This meant that US ships traveling back and forth from Europe or basically anywhere would be sunk by German Submarines. This German policy basically forced the US under Woodrow Wilson to enter the war in 1917.
