After the unification of germany, despite the large amount of german-americans, US politicians weren't a fan of theirs even before ww1- annoyances with Germany attitudes in the pacific and especially around latin america such as the caribbean and venezuela. So the goal is simple: make american politicians favor the kaiserreich and the Central Powers over the Entente with a PoD after German unification but before 1913. What happens? Does America limit her trade with the entente in favor of China and other neutral powers while Germany is more cordial to Washington's interests, letting the kaiser win ww1? Or does nothing change and Willy drags america into the war and spell his own doom?
