Would the United States enter an already-ending war?

Would American forces still enter the war and would the US Marines gain their historical reputation?

The December 1916 branch envisages peace before US entry. The December 1917 branch includes American participation but ends the war before its historical battlefield contribution.

The December 1916 branch envisages peace before American entry. It therefore removes the expeditionary experience associated with the Marines' later wartime reputation. The December 1917 branch instead assumes the United States has entered, but the naval blow brings peace before its forces make their historical battlefield contribution. The proposed reduction in American influence over the settlement follows from that shortened participation.
