What if the Zimmermann telegram and unrestricted submarine warfare were fake and orchestrated by Britain to make US join WW1 on entente side?
Britain uses submarines to sink american cargo and blames the germans, to make things worse they forge the Zimmermann telegram, in a way to make it look legit, but Germany denies it, unlike OTL. The US declares war on Central Powers after that.
But what if the US discovers all that around april 1918, alongside with the discovery of Lusitania having weapons on board.
Which effects it could have? How things would have changed from this?
