What role did Woodrow Wilson want the United States to play in world affairs?

Woodrow Wilson wanted the United States to be a force for
morality and good in international relations.  This can be seen most clearly in his push
for the adoption of his 14 Points at the Paris Peace Conference after
WWI.

Wilson wanted the post-war world to be based on
morals, not on the pursuit of power.  This was his major war aim in WWI.  He was not
interested in taking territory or punishing Germany or anything else.  He wanted to
remake the world on a moral basis that would make war
obsolete.

Wilson believed that the US should be a force for
the realization of his dream of a world order based on morality.
