Woodrow Wilson's speech calling for war on Germany (1917) is one of the famous speeches in American history.

In his speech, there was the famous saying "We must create a safe world for the Lord." The speech is famous for Wilson's assertion that "we have no quarrel with the German people...we enter the war without hostility and without selfish motives." This tolerance and Wilson's promise that victory would bring "the Lord of Universal Justice" helped to win widespread domestic support for entry into the war.

But in fact, the only purpose of the United States' participation in World War I was to make huge war profits (through arms trade). It was precisely because Wilson's ideals and hopes failed to come true that the reality exacerbated the disappointment of the American people after the war.
