U.S. oligarchs HATE competition. They conned the rubes of 1776 to fight the British monarchy so they could have a monopoly on graft in the colonies, the U.S. finally got pulled kicking and screaming into WW1 and WW2 because they hated the competition from Germany et al, and not out of any love for Europe.
