"Uncle Sam" is the familiar icon that <span>was inspired by a 19th century meatpacker from New York and his name was Samuel Wilson. He was the person who supplied barrels of beef to the soldiers of the United States during the war of 1812. I hope that this is the answer that has actually come to your desired help.</span>
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.
