After helping to end World War I and having done his utmost to secure a fair and lasting peace in Europe, including being instrumental in founding the League of Nations.
I like Obama, but what has he done so far to compare to that?
Wilson was the worst president of the 20th century. If it hadn't been for his getting the US involved in the First World War, it is unlikely there would have been a Second.
Woodrow Wilson won the Nobel Price in 1919 (while he was in office).
