Did wilsons 14 point peace plan harm the US?
No, it did not. In fact in 1928 his League of Nations help ratify 65 countries and they agreed that they would not use war a means to win a argument. his 14 point plan helped the world abolish slavery. I contributed towards free trade and no economic barriers. If I were you i would look at what you would define as harming the U.S. I personally think it did the WORLD more good than harm.
