Answer:
not sure what "Cult international political policies" refer to, but the American participation in ww1 was primarily from direct hostility from the germans, especially from the Zimmermann telegram (Germany asking Mexico to invade the southern us), and the sinking of the lusitania by german Uboats. Woodrow had won reelection by campaigning to stay out of the war, so most Americans were reluctant. after the war America became very isolationist, especially when Woodrow wanted the US to join the league of nations(the precursor to the United Nations), which Congress rejected to ratify the treaty, meaning the US would not be a member of the league and pretty much stayed away from international affairs.
