Yes, the United States demonstrated that they were a competitive World Power at the conclusion of World War I.
Explanation:
World War I brought changes not only in the world but in the United States as well. A country not older in politics than other political giants such as Europe, was able to work on global stage like no one imagined.
The United States, under Woodrow's Presidentship played US neutrality until when Germans dashed RMS Lusitania, the British ocena liner, which contained hunderds of Americans on the ship. Germany's repetitive acttions made America to declare war with Germany. This action changed the course of the United States and President Wilson's advocacy for the League of Nations brought recognition to the US as a competitive World Power at the conclusion of WWI.
