The concept of America joining the Central Powers and fighting against the Entente is an often discussed topic on this board, though also one that is often (perhaps rightfully) met with a fair share of skepticism regarding its plausibility. As others have often stated, the US simply had a far greater connection to the Entente (specifically the UK), both culturally and economically, making the prospect of them fighting the Entente rather dubious. But, unlikely as it may be, is there any plausible scenario you can think of in which the US sides with the Central Powers? Would it require significant changes possibly decades prior to the war, or would say, Britain committing a series of diplomatic blunders during the US's period of neutrality be enough to draw them in?
