Your challenge, should you choose to accept it, is to have a German victory in World War I with a POD no later than July 1, 1917.
By "victory", I mean having the Allies sign a treaty of peace with Germany that acknowledges Germany's dominant position in Continental Europe, a restoration of Germany's colonial empire and substantial French and Belgian colonial territory passing into German hands.
Bonus points if the Austrian and Turkish empires emerge from the conflict intact.
