President Roosevelt was highly committed to international cooperation, and in 1935 he fought, unsuccessfully, for U.S. membership in the World Court, the main judicial organ of the United Nations and the one that arbitrates legal disputes among UN member nations.
In fact, the United States has never had an easy relationship with the ICJ, and in 1986 it withdrew from that organ's compulsory jurisdiction, since the court ruled that it owed Nicaragua war reparations after having occupied it between 1912 and 1933.

What was the result of the telephone/telegraph? I think this should be right. It depends on what time period but I remember reading about it a while back in history about how the telephone/telegraph improved communication.
