With the opening of the era of great navigation and the rise of the industrial revolution, machinery completely replaced manual labor, and the output of materials far exceeded the previous total-while the East was unfortunately closed to the outside world-and the center of gravity of the world gradually shifted to Western Europe headed by Britain.

After World War I, Britain and even Europe were exhausted. Regardless of defeat or defeat, they owe money to the United States. The United States has also begun to seek an international status consistent with its economic strength-the Washington Treaty, which stipulates that the US navy can have the same gross tonnage as the British navy, and Britain's maritime hegemony has been weakened.

After the Second World War, Britain shrank around the world and completely gave up its position as the world's hegemon, while the United States, with its strong economic and industrial strength and war funds, shifted its world focus from Western Europe to the east coast of North America.
