I'm having trouble thinking of what Germany and the US would confront each other over, Germany had staked her claim in europe and been stripped of her colonies. Unless Germany goes on a colonial adventure in the americas or their interests collide head on in China.
I think Germany would have its hands full in europe for the time being, trying to keep the Social Democrats from real power (especially after a war costing millions of live which wouldn't have bought many tangible benefits to the people), and perhaps some kind of war/insurgency in Russia (i doubt that they'd want to keep Lenin in power).
Historically, German industry was very expansionist in the period leaidng up to the Great War, with a lot of state support. The US was already getting itchy about German involvement in China and Latin America, and with a German zollverein (cutting America out of the European markets), this owuld only continue, IMO.
