How was the new invention of the U-boat (submarines) a burden to America during the war?
In 1915, the North Sea was declared a war zone and U-boats adopted the policy of unrestricted submarine warfare. The unrestricted submarine warfare enabled Germany the ability to declare destruction on all enemy merchant vessels in the water around Great Britain. The United States wanted the Imperial Government of Germany to be held accountable to the lives lost when Germany sunk the British passenger liner the Lusitania in May 1915 which took the lives of 1,200 people of which 128 were American citizens. However, German Imperial Government tried to state that even though it was sorry for having to take down the Lusitania and the passengers on board it
