As in the title, Do your best to destroy relations between the european entente members and the USA during the course of WW1. The US doesn’t have to join the war or stay neutral, just piss them off the maximum possible degree.
Pissing them off in the peace conference is fine too. Its also fine if its an individual member of the entente and not the whole lot of them.
p.s. please don't make it impossible for the entente to win.
