Answer: Germany was stepping up its efforts to stop goods from reaching the Allies.
Explanation:
After the Lusitania incident in 1915, Germany had pledged to stop unrestricted submarine warfare. They made that pledge to keep the USA from entering the war st that time. But by 1917 Germany went on the offense with submarines again, hoping to end the war and win. However, this was one of the factors that pulled the USA into the war, and Germany lost.
The war changed the economical balance of the world, leaving European countries deep in debt and making the U.S. the leading industrial power and creditor in the world.
The First World War destroyed empires, created numerous new nation-states, encouraged independence movements in Europe’s colonies, forced the United States to become a world power and led directly to Soviet communism and the rise of Hitler. Diplomatic alliances and promises made during the First World War, especially in the Middle East, also came back to haunt Europeans a century later. The balance of power approach to international relations was broken but not shattered. It took the Second World War to bring about sufficient political forces to embark on a revolutionary new approach to inter-state relations.
