Wilson is suggesting that the day for spreading a nations influence as well as its size is long behind, stating that the prime time for the United States to spread influentially in Europe is no longer there. Or in another case no European nation should be able to spread conquest across the continent and that they had their chance. thats the best i can think of hope this helps
Answer:President Wilson is referring to the fact that he wanted world peace, and to have world peace, no country would try to defeat another to increase their power or reputation. The significance of this statement is because he wishes that there wouldn't be another world war (which there was, World War II), and that he wished everybody could work together from then on
