In his speech, wilson makes the following statement: “all the peoples of the world are in effect partners in this interest, and for our own part we see very clearly that unless justice be done to others it will not be done to the program of the world's peace, therefore, is our program…”
how does this quotation and wilson’s speech reveal a changing us position concerning involvement in foreign affairs during and after world war

He is trying to tell that the issue of peace is everyone’s concern.  It is their duty to help others if they expect the same kind of help in the future.  He was urging the American people that the time for isolation is at an end and they must make a choice for it is only a matter of time before this war will come at their doorsteps.

It encourages the Allies on, telling them that a life of justice is impossible to the American people, unless the violations of right are corrected... It also tells them that if the other people did not get treated fairly, then it will continue, and eventually, even we, (the Americans) will not be treated fairly or with justice.

Hope this helps!!
